Most dragon turtles are at least 20 feet wide and 50 feet long, although some can grow substantially larger. These massive, ancient dragon turtles are somnolent, and resemble rocky islands from a distance; their prodigious hoards can be a source of truly ancient sea lore. Legends persist of truly immense dragon turtles who spend centuries drifting on the surface of the ocean, far from established shipping lanes or charted waters, with shells that serve as islands capable of supporting entire ecosystems and even, some claim, small settlements whose inhabitants know nothing of land that doesn't drift across the sea.
