Afagddu
Utter Darkness
The ill-favored child of Ceridwen, whose name means "Dark" or "Ugly" appears so foul to the mortal eye that none may touch him.  In legends a Potion of Knowledge was brewed by the gods for him to drink, but a mortal boy named Gwion drank it instead when he stole the flask from Ceridwen's hut.  Followers are sometimes physically scarred or ugly, unaccepted by society, and therefore angry and resentful.  They haunt the shadows and believe their Dark god is the basis for the Devil in Albion mythology.
Aife
Evil Beauty
Aife was the third wife of Ler, and the evil stepmother of Aehd, Conn, Fiachra, and Finnguala, who transformed them all into swans in the heat of a jealous spite (she is childless herself).  Once her deed was discovered, she transformed herself into a vulture and hunted the lands of Hibernia evermore, in search of the dead to prey upon.
Balor
King of Fomorians
Balor is the one-eyed demon king of surpassing ugliness.  His other eye, hidden beneath a drooping lid, has the power to destroy an army if exposed to sight.  However, the eyelid is so heavy that it would take four strong men to lift it.  In legend he was slain by the son of his own daughter Eithne, the Aon Lugh and his mightly spear.  Today, however, the new truth was discovered.  When adventurers found the artifact known as Lugh's Spear, and removed it from what it was buried within, it awoke the slain god Balor to walk in physical form.  This was found deep in the mysterious Shrouded Isles, where he now dwells, in the perilous depths of the Vale of Balor.
Cailleach Bheur
The Icy Crone
This giantess is associated with Winter and the coming of the Midgardian barbarian hordes.  She is said to be blue in color, and legends tell of her emerging from the frigid mountains on Samhain Eve as an ancient hag, who gradually ages in reverse and disappears at Betain as a young and beautiful maiden.  But during this age, she seduces and corrupts one strong male in a village, who is then forever loyal to the forces of evil.
Efnisien
Unpeaceful Terror
The maternal half-brother to Bendigeidfran and full brother to Nisien, Efnisien is quarrelsome and a natural antagonist.  He is said to be the cause of strife between the two brothers when they were most loving.  Many legends involve Efnisien's cruel participation, including the heinous insult leading to Branwen's punishment (according to prophecy), the slaying of Gwern at the feast of reconciliation, and first hiding the Cauldron of Daghda from the eyes of every god and mortal.
Hafgan
Mortal's Bane
A lord in Annwyn, and a mortal enemy of Arawn, Hafgan the Mortalslayer may only be killed if struck in a single blow; to strike a mercy-blow to his mortally wounded body would mean his revival.  Many heroes in times past have tried to put to rest this murderer of countless innocents, but to no avail.
