Abyssal Exalted have a tendency to possess aberrant personalities. This is because each one of them has a fault in their psyche that allowed Oblivion to enter them. Some leave it relatively dormant, showing only when they perform behaviour that violates the reason they chose to become Abyssals. Others decide to foster this power, which simultaneously becomes a greater and greater part of them. Abyssals who do this are the ones who possess the Avatar Background. Although they may be the chosen weapons of the dead Primordials and their servants, they are beholden to Oblivion, not the Neverborn.
Abyssals do not gain Resonance in the way that other Exalted gain limit. Resonance does not rise from resisting unnatural mental influence or a dominant virtue. Instead each of them has a Virtue Flaw that is what allowed Oblivion to become lodged in their soul at their time of death. In some Abyssals it was always present. In others it only occurred the moment they died, possibly as the result of treachery.
Whenever an Abyssal violates the behaviour of the Virtue Flaw, roll one dice for each point of that Virtue and add one to their Resonance for each success. Also, if they possess the Avatar background, they suffer an immediate Resonance eruption equal to it's value.
