If the idea is that several people are being given magic to shape the world around them, then that's definitely something I could see Discord (either Equestria's Discord or the EqG version, who is still a spirit of chaos who was restrained but was freed when Equestrian magic started seeping in) being the one responsible (perhaps he's aware but still sealed and thus can't do anything himself, thus he sloughs off bits of his power and lets them grow inside of others to cause chaos and eventually free himself).  After all, a bunch of selfish reality-warpers all trying to twist the world to their whims would create chaos in abundance. In that case, he actually probably wouldn't support the player, because even if they go full Bimbo Magic, they're still restrained enough to cause their changes gradually enough that they become innocuous and unnoticed, and thus aren't really causing "chaos" so much as just creating a "new normal." It's not chaos if everybody just nods their heads and accepts it, after all.

In that scenario, the Proprietor of the Violet Room might be a being who is trying to keep Discord locked away (and is perhaps the one who did it in the first place. Ancient human Starswirl? Celestia and Luna's distant but identical ancestors?), but is unable to remove or restrain Discord's power in its human hosts (possibly due to being just a spirit these days), and can't just convince them not to use it (perhaps because Discord made sure his powers would seek out hosts who would be driven to use it, hosts who have the desire to shape the world around them and the willingness to do so even at others' expense). Thus, they instead try to get the player to be their agent to stop the other hosts - perhaps the player has a choice in using the power for their own gain (via bimbofying girls) or not because the Proprietor managed to snag one of the pieces of Discord's power, but was forced to immediately stick it in the closest host they could find to keep it from going free, thus the player wasn't selected specifically by either party (though the Proprietor might lie and try to pretend he was) and can choose how they use their power.

So in that scenario the Proprietor of the Violet Room would actually be counseling responsibility and restraint, or failing that will present themselves as the ones focusing the power to cause the changes, which is a lie meant to keep it happening gradually enough that it creates the scenario of a "new normal," which will at least ensure that Discord doesn't go free. Meanwhile, the little sliver of Discord's power within them might have a mind of its own and will tell them they don't need the Proprietor and should just let loose, bend reality over a table and f*ck it senseless (along with every girl at CHS that catches the player's eye, of course). This would be a bit of a subversion of expectations for Persona players; they're used to always having someone who never lies to them and is always helpful in the form of the Velvet Room's inhabitants. That's actually a standout from the normal Shin Megami Tensei franchise and most of its other spinoffs, so it could be an interesting thing to play with. Especially if a player goes the "no/minimal bimbo" route and thus never learns that they're lying to them, then goes another route where they do find it out.

But in this scenario, I think there would need to be two matrices to decide an ending: both how much you use the bimbo magic and how many "good" endings you get to Social Links (that is, whether they succeed in their personal goals or fail, be that failure be because the player couldn't get the stats to help them enough - you might want to give some indication of what stats you need to have to accomplish something - or because they bimbofied them in such a way that they no longer even care about them (making Twilight a party girl who doesn't even care about school, for example).

So a low bimbo, low good ending ending would be the "worst" end, "The Daily Grind," where your lack of commitment leads you to just drift through a normal life, a job that isn't terrible but not that great, a couple of friends and maybe a lover, but always with the knowledge that you could have had more (though maybe if you got at least one Good End you have a lover who makes it all better, so if not ecstatic with how you're life turned out, you still think it was all worth it). The low bimbo, high good ending would be "A Charmed Life," where your willingness to change yourself rather than selfishly demand the world change around you (by putting in the work to raise your stats and putting yourself out there to help others) leads you to living a happy life with a successful career you enjoy and a large circle of friends (and/or lovers, if we're going with the Persona thing where you can just romance everyone without any real consequence). The high bimbo, low good end is "My Private Heaven," where you've changed people and the world to suit your own ends with no thought for anyone but yourself. But just because you're selfish, does that mean the world you've created is wrong, when everyone's happy and gets along? The high bimbo, high good end is "The New Normal," where through a combination of diligence, magic, altruism and selfishness you've done what every great man tries to do: create a better world. You've helped people attain the things they wanted, and kept their own natures intact; aren't they still themselves, then, pursuing those same dreams? And if everyone's got the bodies of porn stars and are very sexually liberated, well, what's really wrong with that in the end? After all, don't people talk about great men shaping the world? What does it matter if you do it a bit more literally? You certainly put the work in, after all.

The problem is that this kind of requires writing 4 outcomes to every character's story, so for example using Twilight we get:

Low Bimbo, Bad End - Unwilling to bimbofy Twilight (at least past level 2) and unable to convince her to change her self-destructive habits, you end up watching Twilight spiral into either a collapse from exhaustion or a full-on breakdown. Either way, she ends up hospitalized and misses the deadline for her program. You visit her, and at first she's happy to see you (especially if you initiated a romance with her), but soon breaks down crying, convinced she's pushed the rest of her friends away so much that she's lost them and the chance to get into the program, as they haven't come to visit yet. If that seems too depressing, you can have her friends come in at that moment, concerned for her and with assurances that they still care.

Low Bimbo, Good End - If the player uses their high stats to convince Twilight to slow down and accept help from others, she reconnects with her friends and manages to stay healthy and sane and pass her application with flying colors, and her friends hold a party to celebrate. Twilight has learned that no amount of scholastic success is worth shunning all the people who make your life special for.

High Bimbo, Bad End - You've bimbofied Twilight and used your influence over her to convince her to stop caring about the program - and studying entirely. In fact, she doesn't care about anything but having fun with her stud (you), blowing off school and friends alike to be a total party girl.

High Bimbo, Good End - You've bimbofied Twilight, but kept her mind intact and used your influence over her to convince her that her friends and happiness are more important than getting into the program, but still encouraged her to go for it. With support from her friends, far less stress, and still retaining at least most of her prodigious intellect (possibly requiring a lot of studying with a high Int player), Twilight manages to get into the program and throws a big party, later leading to a much smaller one that's just the two of you. Twilight is still the same amazingly intelligent (and often dorky) young woman who's almost sure to succeed at whatever life she chooses and a circle of great friends that she loves dearly - but now she's also a total bombshell with a sky-high libido.

Also, here are some first attempts at descriptions for the cell phone for the Main 6, Sunset Shimmer and Trixie (because why not). Since we don't yet know what the others' stories are gonna be, I made them kind of open-ended, but they should at least serve as placeholders.

Applejack

A true blue cowgirl: honest, hardworking, and stubborn as a mule. Her family owns Sweet Apple Acres, and she's been helping out with the farm since she could walk.

Fluttershy
An animal lover who volunteers at the local shelter. As sweet and kind as she is shy, and she's very, very shy. Worries a lot about the shelter, which is going through hard times.

Pinkie Pie
A living, breathing sugar rush, Pinkie never runs out of energy, jokes or sweets, and shares all of them with everyone, whether they ask or not. Making people happy is her mission in life, and she'll throw a party for someone for just about any occasion.

Rainbow Dash
The ace of just about every sports team in the school, and as much a jock as that implies. You'll never find a more loyal friend, though, even if she sometimes makes things worse trying to help you out.

Rarity
The most fashionable girl in school who doesn't follow the trends, she makes them. Literally; she dreams of being a designer. Only a tiny bit stuck up, and very generous to those in need of her help, especially tips on style.

Sunset Shimmer
The former "queen" of Canterlot High, who ruled through bullying and blackmail. Apparently had a change of heart, though a lot of students aren't buying it. Worried she'll never move past her bad decisions.

Trixie
That's "The Great and Powerful Trixie" to you! A self-proclaimed (stage) magician who's about 20% actual talent, 80% ego. More than a little miffed that she's been left out of all the "real" magic going around lately.

Twilight Sparkle
Canterlot High's resident bookworm. Still new to the whole "social life and friends" thing. Studious and diligent to the point of obsession.

Hello!

I'd love to take up the mantle of writing some bimbofication scenes. If someone can give me a rough timeline of how 'bimboed' each step of the process makes the girls, I can write the transformation process. Also, I'd be happy to write some other characters if it's needed, though I've only seen up the end of season three. Any characters introduced thereafter are a little unfamiliar to me, I'm afraid, but everyone else is fair game! Which of the girls is highly sought after?

I'm thinking of writing a replacement for Todd Howard, I just have a question. For the Todd Howard replacement NPC and their introduction to the player, are there any basic things we should stick to when writing or do we have free range to write and post it here and just change it from there?

Hello, I'm Pickleless! I'm a writer on FIMfiction, a big fan of Annon, and bimbo stuff in general. Checking my FIM account, you would see I'm a comedy writer, not a smut one, but I have a lot of free time right now, and it doesn't look like that'll change anytime soon. I would love to contribute to this in anyway possible. Heck, I wouldn't mind using this as an excuse to start learning code or drawing if this stays alive and I get good enough to contribute something worthwhile. At the moment though, I'm just a writer and I'd like to give a hand if you'll have me.

Since reading this I was trying to think of a good excuse for why the main character has this power and where he could have got it. Since everyone else is throwing out their ideas I figure I should just pitch mine as well off the bat. Dev said he's only seen season 1 so I'm gonna cover some canon stuff at times.

So, in canon, just about every character in the human world is a counterpart to someone in Equestria. Since that's the case, why not have the main character be a counterpart of a Changeling? Changelings in MLP are creatures that feed off love, and use it to power their magic and make it stronger.  In this game, Twilight seems to be a mix of her human self and pony counterpart, I also assume she originates from the human world. Since this isn't following canon too closely, why not have Sunset steal the Element of Friendship as she runs away into this world for the first time? She bumps into the Main Character, and drops the element. The main character picks it up and it jump-starts his changeling magic and makes it more 'friendship' based, adding to the dating sim aspect. The Element of Friendship could also be a pendent in this version instead of a crown so he could wear it at all times and not have it be visible or stand out.

MetaKnight suggested having the Lust Statue being the entity who you use in the Violet Room, with you being it's chosen one to spread lust and whatnot. In canon, Starswirl banished the Sirens into the human world so they weren't Equestria's problem anymore. You could have the Lust Statue be an entity that was turned to stone like Discord, and banished. Combined with the changeling and crown thing above, it would also make more sense why it would choose you as it's chosen one. The Violet Room could be a place it made so it could reach you easy without having people bother or mess with it.

Even if you're not fond of this idea, I still would love to help brainstorm, and help write ero scenes that you need or want at the moment. So please don't hesitate to ask!

Hey... You guys need any more writers? I did some work for that thing Shite Life was working on, Bimbo Canterlot High, but that project's basically dead now.
