Returning from a hunting trip to find your lands in ruin, you must rebuild your home while fending off hordes of monsters that attack your gates every night. Should your city fall and the forces of darkness sweep across the land, you will awaken to begin a new run where you carry forward the rewards of prior attempts – more heroes at your disposal, previously unexplored lands already uncovered, and every opportunity to push further as you uncover the mystery that has you trapped in a never-ending cycle of life and death.
