Pool of Nemhain

"Find the Pool of Nemhain, whose waters are as black as night and as still as death itself."

- The Dochraid to Morgana

The Pool of Nemhain is a lake in the land of Albion. It is the last of the Five Gateways separating the living world from the world of the dead.

History
When Morgana sought to prevent Gwen and Arthur's marriage, the Dochraid advised her to travel to the Pool of Nemhain. There, Morgana used a magical coin given to her by her late sister to summon Lancelot from the dead as a Shade (Lancelot du Lac).

Trivia

 * As a Gateway to the Spirit World, it is likely that the pool is guarded by the Cailleach, the Gatekeeper to the Spirit World (The Darkest Hour).
 * In Irish mythology, Neman or Nemain (modern spelling: Neamhan, Neamhain) is a spirit-woman or goddess who personifies the frenzied havoc of war. In the ancient texts where the group of death goddesses known as The Morrígan appears as a trio — the three sisters who make up the Morrígna — one of these sisters is sometimes known as Nemain.
