In the harsh region known as the borderlands, humans wage an endless war against demi-human creatures that attack them relentlessly, determined to seize their land and their gods. A young boy named Kai, striving to defend his village, suffers a life-threatening injury that triggers the return of memories from a past life. If you're not a guardian bearer, it's like you're playing life on hard mode... Kai's newly acquired knowledge provides him with a fresh perspective on the unfair "rule set" that governs the world around him. One thing is clear: For those without a god to serve as their guardian, life is a constant struggle for survival. Thus begins the epic tale of a young boy's rise into a vast world filled with magic, bloodshed, and mystery.
