Pool of Nemhain

The Pool of Nemhain is the last of the Five Gateways that separate the world of the living from the world of the dead (the Spirit World). The waters of this lake are as black as night, and still as death itself.

Morgana, High Priestess of the Triple Goddess, went to the Dochraid to ask her how to raise a Shade with a magical coin given her by her sister Morgause. The Dochraid told her to travel to this place and cast the coin into the lake's depths, so that her wish would have been granted (Lancelot Du Lac).
