Zellare
Prime Dragon of Fire
Zellare was the Prime Dragon of Fire, whom X'dir considered the strongest of the four. He helped Zelgarius seal Desoloth, but X'dir later leads the Hero against him to break that seal. Zellare's death leaves the High Priest of Fire shaken as Desoloth threatens Etherstorm.
