Vance

Vance is one of the four overseers of each individual area, the area he occupies is Prota. Unlike the other NPCs, their dialog changes when specific events occur, like when you get the key to the next area, when the ending is activated, and when you attempt to unmask them.

His first interaction makes it seem like he knows who Limbo was without clarifying anything apart from how he spoke to Limbo and seems casual as he gives a vague comment after the player acquires the key to Trita.

When the ending is activated after the void, he urges Limbo to actually end things or "get lost" and if trying to unmask him, Vance implies some sort of hesitation from Limbo that makes him weak for the attempt before suggesting he himself would break Limbo's wrist if he didn't have any sympathy.

His SE sounds like a genuine chuckle and was mistaken by a playtester, close to the creator, to be the voice of another friend rather than CR.

Appearance
Vance has a fair skin tone with his short straight black hair being parted to the left side. His mask has two triangles that curve inward at the bottom for eye holes and a large shark-toothed grin that curves inwards at the ends. The t-shirt he's wearing is a tan v-neck with a diamond on it for Prota that seems a bit small on him when compared to the others, aside from that, he's also wearing blue pants with grey dress shoes.
