The Tower of Gods is a massive building constructed by the Ancient Ones that stands tall over the surrounding jungle. It is said that inside this tower are numerous artifacts that can grant any wish one desires. However, in order for a wish to be granted, the individual must first pass the Trial of the Guardian - a battle with the enigmatic ancient creature that resides in the shadow of the tower. Few have faced this beast and lived to tell their tale. The stories that follow are about courageous young girls who are willing to risk their lives for a wish that is worth dying for.
