The Iron Legion
The Iron Legion is a group of rogue Warforged, who were captured by the Beholder Sovereignty during their war with the Starforge Empire and brainwashed into turning on their creators. However, something went wrong during the ritual and the Legion now mercilessly attacks everything it sees. They cannot be bargained with. They can't be reasoned with. They don't feel pity, or remorse, or fear. And they will absolutely not stop…ever, until everyone is dead.
