"Years ago, when the Jade Wind froze the sea, a demon of nightmares was trapped below the sea's hardened waters. A group of Luxons unearthed the demon's resting place while mining the sea for jade and other resources. The demon's nightmares slowly seeped into their minds, until they eventually went insane. The tale of these outcasts is a sad one, but if you come across any, do not show them pity. They are beyond rehabilitation and will not hesitate to kill you.
The demon that caused the corruption of these outcasts is known by the name Kanaxai, bringer of despair. He is also the source of the Oni that appear all over Cantha as waking nightmares. If you wish to prove your loyalty to the Luxons, head into the caves known as the Deep that lead toward the ancient mine, and destroy the outcasts and the demon Kanaxai."
Eurayle's name may be a misspelling of Euryale, a Greek name which means 'far-roaming'. Euryale is the name of the nymph Euryale, mother of Orion, and the gorgon Euryale.
