Terratoise

Terratoises were a native species to Kethsi. Very little is known of them, other than Dathana describing the Stone of Jas in her message "patterned as if it were a great terratoise shell". This, in addition to their name, implies that they were a Kethsian equivalent to tortoises. They presumably went extinct after the Dragonkin destroyed the entire realm of Kethsi and terratoises with it.

Trivia

 * 'Terratoise' is a portmanteau of words 'terra', a Latin world for earth, and 'tortoise'.
