As my character, Purgatory would put it:
'This is hell. The flesh does not matter. The flesh is already dead. What seems like a hand, or a leg, or, in Farrago's case, a wing, is really just the
memory of that limb, constructed of solidified thoughts and emotions. Thus, if somebody takes a physical wound in the afterlife, it eventually closes. Bleeding ceases, limbs regrow. Until the soul has once again reached the state it was in when it arrived there, until it once again matches the memory pattern.
But if anyone suffers an
emotional wound...the effects are more permanent. The memory pattern, the
blueprint for the body, so to speak, changes, and these wounds do not heal.
Thus, Farrago was wounded more in mind than in body when she lost her wings.'
Then again, Purgatory talks too f***ing much
