I recommend that you should read through build 3.1 until the "7 days left" day to understand this and for context ( most these paragraphs are from the help of google and other search engines)
SPOILERS AHEAD
You have been warned
This update is giving a headache of who is the mastermind behind it but in this same update I have a theory of what the future may hold and who it might be considering what is said in the beginning of the 7 days left prompt of us.
Since they said the one who talked in the dream,in which there are Valor, Courage, Compassion, and Innocence. That 2 had fallen and 2 remain and considering the colors of the text might have been hinting who we are talking to from the previous nights.
All 4 of them are traits of humans and all for of them are considered as "Virtues" but in this novel manipulation is of the big part of this murder mystery. One big example stated in the novel is putting all of the advocates against one another as the presumed motive of the killer is disharmony and chaos of the advocates of different planets and putting this into perspective, there are some ways of these "Virtues" can be used or attain this goal
1.Valor/Courage- These traits are synonymous to each other due to their concepts overlapping but the main difference between them are Valor is more specific in being the "Hero of the story" or similar tropes and Courage being confronting fears in any context. In which both of these can be used to manipulate people on being
Misguided Actions
When valor and courage are misdirected or manipulated, individuals can be persuaded to engage in harmful actions under the mistaken belief that their actions are justified or serve a greater cause. In these instances, genuine bravery is present, but it is detached from ethical considerations. The outcome is the application of inner strength towards destructive or negative outcomes (these are from google)
Compassion- This trait is defined as the deep awareness of and sympathy for another person's suffering or misfortune, coupled with a genuine desire and motivation to take action to alleviate or end that suffering. Even though this trait is helping others it can also be used to manipulate people one example of this is
Exploitation of Trust
Compassionate people, being naturally trusting and helpful, can be easily taken advantage of by individuals who feign need or distress for personal gain.
Innocence - refers to a state of being free from moral wrongdoing, guilt, or sin. It implies purity of heart and mind, and an unfamiliarity with the negative, complex, or darker aspects of human nature and the world. And one big example of manipulation can be used in this is
Emotional Blackmail and Guilt
A manipulator can leverage the innocent person's purity of intent against them. They might imply that questioning the manipulator is "unkind" or "wrong," making the innocent person feel guilty for having any doubts. This prevents them from trusting their own instincts.
The examples I given to each trait are some ways the characters in the game can/might use for the disharmony of the advocates and mostly I've observed of the characters like Valor and Courage maybe manipulating the MC and Kai(due to one quote that something is saying the Vul is the killer) to some extent. Or Arcadia and her brother using Compassion and Innocence(This one is a stretch).
And what the voice (in which I suspect to be Innocence) said that 2 Have fallen and 2 Remain might have been a lie since there have been colored text with the same color as the other traits due to mainly the nightmare of the other night and what Kai's word of him suspecting who the killer he think is. And thinking someone is innocent is not the same as them being trustworthy.
That's all I could think of since the story haven't finished yet and I'm sorry if this post is kind of a mess it's literally 3 am me writing this so forgive me.
