Shackled by darkness

Welcome to the Nepilim Academy!
Immerse yourself in the spectral world where monsters pursue you by heels, reality is a maze of pain and blood, and all goals come down to one - survive.

No one knows if my keeper is alive or dead ... except me.
For several months I hid that he went in search of his sister. The moment came when he needed help. But the distance between us cannot be overcome by one wave of my wings.
In an attempt to find the styl, I turned out to be a captive of the enemy fortress. Thorne - the ruler of terrible monsters - decided to persuade me to his side and make an ally. He knows something about my origin, and revealing this secret is too much temptation.

The boundaries between the kingdoms are erased. My world is burning in fire. And this time I"m not sure that I can fight darkness alone
