Cardon is a warrior found on the seventh level of the Abyss. The Avatar found Cardon right after entering the seventh level of the Abyss in Ultima Underworld I. Cardon had been wounded and the Avatar gave him a healing potion, before they talked. Cardon told the Avatar of how Tyball was sapping all the mana on the level and his hordes of monsters having erected checkpoints through the corridors. He had a medallion of passage to get by them, but had lost it in the mines to the east.
