Rajh

Rajh is one of the guardians of the Halls of Origination. Like the other constructs within the halls, Rajh was created to protect the powerful device capable of resetting all life on Azeroth. Each of the keepers has a sphere of influence. Isiset presides over magic; Rahj, the sun; Setesh, chaos; and Ammunae, life.
