Adventures at these levels have far-reaching consequences, possibly determining the fate of millions in the Material Plane and even places beyond. Characters traverse otherworldly realms and explore demiplanes and other extraplanar locales, where they fight savage balor demons, titans, archdevils, lich archmages, and even avatars of the gods themselves. The dragons they encounter are wyrms of tremendous power, whose sleep troubles kingdoms and whose waking threatens existence itself.
