Seru

Seru are magical creatures that roam the world. During one period in time, humans and Seru had worked together, but, due to the Mist, the Seru had gone berserk, and began to attack the humans. Aside from these Seru, there are also Seru that are immune to the Mist's evil powers, the Ra-Seru. These Seru lay dorment in Genesis Trees until they were eventually found by humans, namely Vahn, Noa, and Gala.
