Grendel

The Titan, the God of Destruction, the Embodiment of Ruin. Grendel is the most powerful known entity in all of U'rth, more of a force of nature than a living creature, and the bane of all civilization. No one knows how this horror ever came to be; Some believe he was born with the Cataclysm, or that he existed even before. Some say he is but a raging god coming down to punish all. And some even whisper it could have been human once. All that is certain is that Grendel has always been there, terrorizing the civilized races for hundreds of centuries, and it's an ever-likely possibility that he always will be.

It was Grendel who wiped out the ancient empire of the fey races. It was Grendel who killed the mythical hero John Ymir after a grueling battle. It is him who brings unparalleled destruction across the lands, crushing, incinerating, disintegrating, devouring everything in his path with a fury that burns like the most restless volcano. Periodically, the Titan appears to satisfy its hunger for death, and retires to areas unknown for potential years at a time. But in the end he always returns, and with him comes the endless cycle of ruination

Again and again the civilized races of the world have tried to end him, but every single attempt across the ages has failed, only managing to slow him down in the best of chances. The colossal losses of life continue to ever grow, and even thought the plans to finally vanquish such a terror never have ceased either, many of those that live begin to think that resigning to a fate under Grendel's unending wrath might be the only path left...
