There was once creatures that existed in the world of Equstria...their names? Humans. They had one purpose on their mind, worship of the god Zalugon, the ancient god of the undead, one day Zalugon used his magic to transform his cult into an army of undead demons with the power of immortality and there was only one hero to defeat them, and he defeated the monsters with a skill known as the Azaku, a powerful god spell that could summon a blade to kill immortals.

However, after being defeated they have finally returned, now Apple Bloom finds out she is related to the hero in the past and has the same powers as he had, now she is the last hope of Equstria will she prevail over evil or will she fail and lose everything she loves and holds dear?
