The Old Temple
This temple, ancient beyond reckoning, is situated in a central yet secluded location deep within the jungle. Until recently, it was the site of powerful Eldritch ward, rumored to have kept the primal magics of the world at bay, preventing them from wreaking havoc upon the world. Upon the sundering of this ward by the dread emperor Jimmu, the world is at risk of being flooded with primal cosmic energies.
The ancient ward of the temple was forged by the sacrifice of five heroes, the Core, Forest, Winter, Tempest and Depths guardians, who sacrificed their mortal souls to create it. With the ward gone, however, vestiges of these guardians, corrupted by the primal energies their souls defended against, were released; while some of them have been destroyed, others escaped, their whereabouts unknown.
