Because he felt nothing

Asmodi has always considered himself an apex predator, the wyvern above all wyverns who's only wrong was deciding never to take a mate and produce offsprings of his own but when his nephews bring a human family into his teritory to shelter them from the storm outside he finds himself with the biggest thorn in his side. Elizabeth, a girl he's labeled a human corpse has forced herself into his life by trying to commit suicide on his forbidden basilisk.

Note: Asmodi is pronounced Asmod-die, not Asmod-dih as some thought. Sorry for the confusion.
