The humans have taught her many things over the centuries.
Betrayal. Loss. Grief so overwhelming that she wished she had not hidden herself away, that she had crumbled to painless stone with her kin.
Fear. Pain. Horror at seeing the glow of dawn on the horizon, knowing that the day would bring healing, give them a fresh canvas to work on come nightfall.
Deception. Betrayal. That trust was a fool's game, one that she dared not play if she intended to survive.
Yes, Demona has learned many lessons over the centuries.
She intends to pay them all back, with interest.
