The realm of the Raven Queen, a layover for souls on their way to whatever lies next. Endlessly gray and same, save for a hill with a tree and a river.
Season 12
Seen after Roux died to the Frost-Forged Dragon and Vanja attempted to Revive him. They were taken to a gray misty land before a woman with a gray cloak, pomegranate-colored hair and a raven on her shoulder and her guardian, another woman with toothy mask, where Bax made his bargain to trade his life for Roux’s.
Season 13
Echoingly empty with nary a soul, nor the erstwhile ruler. Sylas wandered here alone for an unknown time until Tala appeared and they were able to find a Door to the Between instead.
