It's a bit unclear what's going on with Brianian. It seems they find their existence doesn't make much sense, and a lot of things go... strange, very strange. But that doesn’t stop them from accidentally discovering the secrets of strange worlds or realms. Many citizens don't understand him at all. Personality-wise, he sounds quite insane, but in a monotone, serious way. This might be because many thoughts are constantly passing through his "brain".
