Also known as Esotuk, large foraging creatures living on remote island of Riri. Make a one time in life migration to Tarma but always drown just before shore. Create a crystal in skull that is swept or directed by forces back to Riri. Riri's foundations are made of these crystals, and the island is upon it. Riri is protected by the strange energy given off by these crystals. Esaten eat trees. Are not creatures of Yaial, but in fact aliens transported through the original Orset crystal they contribute to.
