"Dweller"

Dweller is a permanent agent hidden in Metru Nui, and has been monitoring the city almost since it was ruined in the Great Cataclysm. From his hidden base in the Archives, he can probe the thoughts of others or drive them mad through nightmares. He can also affect others' perceptions to keep them from noticing him, and he has been able to spend nearly a thousand years undetected. With news that the Toa Nuva have left the city, Dweller has a new mission: track and eliminate Toa Takanuva.
