Raven

Ravens were black birds similar to crows. They were opportunistic eaters, feeding on carrion, insects, grains, fruits, and small animals. These birds thrived in most northern climates and were very long-lived, making them ideal pets and companions.

Ecology
A large number of ravens lived in the asteroid known as the Castle, in the center of the Tears of Selûne.

The Raven Queen commanded numerous flocks of ravens from her divine realm in the Shadowfell. The ravens acted as the Queen's scouts and messengers across the multiverse, also alerting and guiding her shadar-kai servants to the location of items and memories that she wished to collect.
