Vivian

Vivian is a recurring demon in the series.

History
The Lady of the Lake, otherwise known as Vivian or Nimue, is a fae Lake Maiden that is famous in English lore for giving Arthur the blade Excalibur along with enchanting Merlin and raising Lancelot after his father's death. The Lady of the Lake is usually referred to by various spellings of her other names. In some depictions, the Lady of the Lake is a title belonging to both Vivian and Nimue.

Merlin had met Nimue at the Fountain of Barenton (Brittany) and fallen so deeply in love with her that he agreed to teach her all his mystical powers. Nimue became Merlin's scribe, who recorded his prophecies, as well as his lover. Unfortunately however, over the years, Nimue became so powerful that her magical skills outshone even her teacher and she imprisoned him in Glass Tower. In English legend, she was said to be slain by Balin.

To some extent she stepped into Merlin's role at King Arthur's side, but the old man's removal contributed considerably to the great monarch's downfall. Vivian was eventually obliged to reclaim her sword when Arthur was fatally wounded at the Battle of Camlann and Excalibur was hurled back to misty waters. She was later one of the three Queens who escorted the King to Avalon.

Since Nimue's place as Merlin's student and lover was largely overtaken by Morgan Le Fay, a lady whose very name in Breton indicates a water-nymph, it seems that the two were once aspects of the same character. As both appear among the three queens who escort Arthur to Avalon, she no doubt had a third aspect making up the well-known theme of a Celtic Triple-Goddess.

Nimue is thought to be related to Mneme, the shortened form of Mnemosyne, one of the nine water-nymph Muses of Greco-Roman Mythology who gave weapons, not unlike Arthur's sword, to the heroic Perseus.
