(Giant Trunk) Mutated Satior

Lore
Satior learned of ruins where forsaken beings like him gathered. Though unaware of its location, he crushed mountains and crossed oceans in search of a place where he might be freed from his loneliness. In his unbridled hope, he forgot to consider that the ruins might not be be large enough to contain his massive girth.
