From publisher blurb:
For a level 19 party!
When the forces of chaos threaten to unleash a primordial titan upon the world, the party must scramble to undo their awful work. This creature has been prophesied to rise from the Great Well of New Moon’s Rise, a nature temple which overlooks the ocean. However, the problem isn’t finding where to stop the forces of chaos, but when. The chaos infesting the temple has caused time itself to become quite unstable; now past, present, and future collide as part of chaos’ plan!
Fortunately, if anyone can stop the titan from emerging from the temple, it’s the party. They’ve proven they can overcome the odds, time and time again throughout their illustrious careers. New Moon’s Rise may be their biggest challenge yet, but there awaits familiar allies who really push the meaning of "self-dependence."
