The Behemoth is a massive quadripedal creature created by the Great Tree of Erebus. It was one of the first creatures to inhabit Erebus and has trekked great distances across the world, creating large rivers and canyons as it did. This stone-faced creature was once very docile and even kind, acting somewhat as a guardian for the smallest creatures of Erebus. That changed when Firis seized control of Erebus and the tree that had created it. Firis attempted to use the Great Seed from the tree to control the Behemoth but it was too strong. Instead, Firis cast it into a deep sleep and overtime, the Seed drained the beasts willpower, leaving it as a one of the first of Firis' army. When the day came to invade Albion, Firis awakened the Behemoth and used it to break down the walls of every kingdom on the planet.
