The Black Knight

Sir Locke became the Black Knight after drinking the black, bloody ooze in the Temple of Dusk. He later sided with Bane and battled Morgana, Mordred, and Artorias. He escaped the temple after nearly perishing in combat.

After the temple sunk, the corrupted Locke transformed into the Black Knight and brought darkness to the region around Gwynneth. It is uncertain whether he slew his own mother, the Elf Queen Gwyn, or if she had escaped before he laid waste to the townspeople.

Rumors of the Black Knight working with the Tower of the Forsaken have persisted from the few who escaped Gwynneth. The region around the lake is dangerous and filled with vile things.
