The Dragon-Tooth Isles are a rugged, isolated archipelago shrouded in eternal fog and ancient myth. Sharp, mountain-like peaks rise violently from the ocean, resembling the jagged teeth of a colossal beast. This primordial wilderness hosts giant redwoods and ancient ferns that have stood untouched for eons. Explorers find themselves in a vertical world where the environment is as dangerous as the leviathans dwelling in the deep trenches surrounding the land.
