Raven Queen

The Raven Queen is a mysterious entity from the Shadowfell who is revered as a deity by the shadar-kai. The whole existence of the Raven Queen is focused on collecting memories and strong emotions, typically associated with loss and tragedy. To that end, she dispatchs shadar-kai to the far confines of the multiverse to wait for such an event to unfold, as scouted by her ravens. Then they collect mementos, such as trinkets, memories from the living and sometimes the souls of the dead, and bringt them back to her.

The Raven Queen also claimed domain of the souls of all shadar-kai, which always returned to her after their deaths

She was said to have forged the first weapons infused with shadow magic.
