Haunted by the shadows of her past lives, Syndrah Tri-Garon must conquer the deadliest trials of the dark realm or be consumed by her own soul. Faced with her final opportunity to be accepted into her village, Syn must complete a task to prove her worthiness-a human sacrifice to ward off the bloodthirsty monsters that lurk on the other side of the portal. However, things don't go as planned when her haunting strikes amid the sacrifice, resulting in a devastating attack on her village.
Faced with no other option, Syn journeys into the portal of horrors to seek redemption.
