Turtles of the Great Underground Empire can grow to enormous size and have incredible longevity. One such turtle, residing on the beach near Largoneth, was once the favored pet of King Mumbo II (and the basis of his bloit).
This turtle helped an enchanter defeat the Warlock Krill in the 940s, and was particularly proud of his rainbowcolored shell, an enchantment cast on him in the 860s.
