Tortle

Tortles are a race of intelligent tortoise-like humanoids indigenous to the southern islands of the West Isles.
Tortles are reptilian-looking humanoids with large shells on their backs that are capable of containing their entire bodies. They had leathery skins that varied between olive-green to blue-green hues. The dorsal portion of their shells is usually darker than their skins, while the ventral portion was lighter, usually with yellowish tones.
Tortles rarely wear any clothing, favoring instead belts and harnesses to carry their belongings. They had little tolerance for cold, and usually migrated away from temperate areas when winter approached.
Although generally poor swimmers, tortles are capable of floating on water and can hold their breath for over an hour. Their high buoyancy grants them the ability to cross swamps, mud, and quicksand with little difficulty.
Most tortles had the notion of having their houses on their backs, which meant that they rarely felt homesick or the need to lay roots in any single place. They are eager to learn new customs and find beauty in the most ordinary things. Despite spending much of their lives isolated, tortles like to form strong friendships.
Besides being able to wield weapons and shields, tortles have claws and beaks that were effective as natural weapons. In addition, they can retreat into their shells for additional protection if necessary. When withdrawn in this way, they are unable to move and see, but could still hear and smell the outside world. The shape of their bodies make it impossible for tortles to wear armor, however.
Tortles only reproduce near the end of their natural lifespans. When their young hatch from their eggs, they spend the remainder of their lives sharing all their life experiences and teaching survival skills. Young tortles will become orphans after about one year, by which time they are expected to be able to fend for themselves.
Usually keeping to themselves, they tended to live alone, but keep in close contact with their community. Tortle villages are typically welcoming of humans, halflings, and elves.
