Hey this short guide will explain the base lore setting of the game, mainly the difference between the main regions, keep these informations here in mind when creating your character so you can fit with the ongoing story properly!
In Wisteria we roleplay in a fictional reality, 30 years before the Red's adventure when the Pokemon League was giving its first steps and Oak was just an aspiring young assistent. As soon as the league grew in power and relevancy in Kanto they started exporting their ideals and investing and building gyms in the neightboor region, starting off in the city of Olivine, however they should face a cultural clash in this expansion attempt!
The social-economic situation of Kanto made itself a fertile ground for the League's growth, but this shouldn't be the same in Johto!
(Kanto in the previous century had a democratic govern with a very economy based set up, with Rocket Corporation heading the production and distribution of items, Zilph heading researches and invention of technology and the Govern with social-safety issues, however these three giants constantly bite eachother with conflicts that resulted in social crisis and delay on developments, those crisis made people receive well the ideals of the league that would change the world forever)
Johto's recent past is different, the whole region is organized with millenial traditions, the people culturaly values arts and is ruled by the Ecruteak Dojo, with a way more centralized power, the Dojo organizes the social-safety aspects of the society, schools and traditions taughts, and also the distribution and production of goods. However Johto doesn't receive alot of investments into discovering new technologies and this is where the league saw their opening, investing in Olivine they bought first a lighthouse and converted it into a laboratory, that also works as a tower for PokePhones to work in the region.
Before the arrival of the league, you might be wondering how the society of Johto dealed with pokemon? This is exactly where I wanna get: Pokemons were seen as divine beings even when tied to social roles (when used as work forces) however to the generic Johtoian it isn't expected to own their own pokemon unless they have relevant social roles in their town or are simply defined worthy by the traditions.
Also one noticeable cultural shock in Johto is the fact that the traditions incentive and hosts Pokemon Sacrifices (Extract and removal of items) through the region, and the body pieces (resulting items) are usually given to the Ecruteak Dojo after peregrinations through the region (This is paid back with money). This tradition is also the way Johto manages to handle resources and factory production to multiple uses including militar (Samurai tools) (The method of the Sacrifice is up to the roleplayer to do, you guys can make rituals events etc, as there are multiple different tradition across the region, but its known that they take the bodyparts to the dojo (and sell them to the dojo master))
League/Kantonian in general are averse to Pokemon murderers and this should be a conflictual point (Extract and removal of items)(This isnt a black/white moral kind of thing, Johtonian were taught through milleniums that those sacrifices helps to keep the order and keep the gods calm, while we outsiders can easily see this is some sort of $$ to the Dojo)
Now lets go back to the recent days in Johto (30 years before red's adventure): The league managed through the years to grow in influence and relevancy thanks to the adventun of PokePhone and the LightHouse Lab and in the last years finished building the gyms in Olivine, Goldenrod, Mahoganny and Blackthorn cities. (spreading the ideas of pokemon training as a sport) Once the gyms were stablished and pokemon training (as sport) was introduced in the society as an idea, thats where the league moved on their next step (this actually happens in close paralel in Kanto) wich is: distributing pokemon partners to the society and also distribute them on huge packages to local stores and places with workers/gifts, making having a pokemon something way more common.
These movements wasn't ignored by the Dojo. When the league was building the gyms and spreading the pokemon sports, they converted one of the ecruteak building into a gym themselves to prevent the league to raise influence in their own town. (Ecruteak Gym is controled by Dojo not the league) since they also used to raise and distribute pokemon the Dojo master is also hosting their own give-away classes to cityzens and taking the chance to teach their traditions and avoid further poisoning from the foreigners.
This is the moment in the story where having a pokemon becomes more common, and where our gameplay starts.
Now you have the setting knowledge enough to start thinking on how to design your character be him/her a native Johtonian or a Kantonian, feel free to ask questions in our discord!
