A mysterious genderless being that appears in dreams. They lack any and all memories of the past. That said, they do have some vague impressions of feelings towards people they've met in the past or feel they are connected to. They almost always have a snarky quip for every situation, with a particularly sharp tongue toward authority figures. While not overly narcissistic, Arval is quite proud of their abilities. Arval has a very strategic mind and sometimes comes up with plans.
