Celani

In the beginning of Creation, Ayar created the Aldar, an immortal race only less powerful than the Gods. After the War of Chaos, the Aldar were allowed to retire to a plane of their own, and those who left were never seen again. However, a group of Aldar led by Han-Tolneth begged to remain and serve the Gods. These were renamed Celani, and to this day they are the servants and companions of the Gods.
