The Afanc (Avanc, Addanc) is a creature from Welsh folklore that lives in lakes. It's description differs highly ranging from dwarf, beaver, crocodile, and is sometimes said to be a demon but it is most favourably depicted as a large frog with claws on all limbs.

Regardless of he depiction, Afanc is a monstrous creature that, like most lake monsters, was said to prey upon any foolish enough to fall into or swim in its lake.

In Myth

The most common story that surrounds it is a town is plagued with its carnivourous activities so much that they resolve if they cannot kill it they shall take it to another lake away from them. They employ the Afanc's one weakness, a beautiful woman who lures the Afanc to sleep upon her lap. The villagers then bind the Afanc with magical chains and use two oxen to drag the creature across to the next lake. The brave woman's name in this story is not remembered which is a pity considering that in the struggle with the Afanc to chain it. In the story it tore off one of her breasts.

Some later legends say that once the creature was dragged out of the lake he became powerless and was killed by Peredus, or King Arthur depending on which tale you read. Close to Llyn Barfog in Snowdonia, is a hoof-print petresomatoglyph etched deep into the rock "Carn March Arthur", or the "Stone of Arthur's Horse", which was supposedly made by King Arthur's mount, Liamrai, when it was hauling the Afanc from the lake. Lolo Morganwg put forth a tale in which the creature's thrashings caused massive flooding which ultimately drowned all inhabitants of Britain except for two people, Dwyfan and Dwyfach, from whom the later inhabitants of Prydain descended.

Powers and Abilities

The Afanc is sometimes said to have magical powers and even the ability to speak Welsh. In one tale it uses these powers to turn its thrashing of the lake into the mythical deluge that appears in many mythologies.

In BBC Merlin

Afanc appeared in BBC Merlin TV Series as main villain in episode The Mark of Nimueh where Nimue, the main antagonist of Season 1 conjures Afanc as powerful golem out of water and earth element and unleashed upon Camelot to wipe out it's population via plague that it carries. Eventually Merlin and Gaius discovered the Afanc. With the help of Arthur Pendragon and Morgana, Merlin was able to destroy the creature using his own elemental magic by combining the blast of fire and wind, destroyed it. The shell that used to conjure iit later discovered by Uther, in which he realized that Nimueh sought to destroy the kingdom.
