And If You Cannot Bring Yourself to Kill (слэш)

Xiao is the name he was given upon his new contract with the great dragon Rex Lapis, but before that, he was Alatus, a weak adeptus twisted to the whim of the God of Dreams. The blood on his hands and karmic debt on his shoulders corrupt his Heart and drive him toward death, until he happens across an otherworldly light stumbling through a lonely valley.
Aether has visited and fled more worlds than he can count, careful never to get attached, but this is the first time he's truly been trapped on any one of them, stripped of his power and split from his sister. He is certain he will starve and fade, chained by his immortality to a life of unending agony, unable to even put himself to rest— until he meets a lost and achingly gentle adeptus who brings him new hope.
It will be a long time before either of them learn how to receive the love they are given.
