The Eldrin were a race of gods which appeared in the late Primordial Era. They were led by the Green Warden, and were responsible for the shaping of Vaeheim into a paradise. Among the Eldrin were Cirion, Velya, and a multitude of other unnamed spirits. 

The Eldrin ruled Tarn during the Eldrinic Age, before Ereus and the Avalar assumed rulership of the world.
