Fuelle, the Dark Bishop, was a former trustworthy priest of Dotnia Kingdom. He has been corrupted, however, by the power of the Dark Orb. Fuelle stole the Dark Orb and ran off to the tower north of the castle. Here he drains the dark power from the Dark Orb, until it consumes him and releases Onyx, the Dark King. Fuelle must be fought again if Onyx defeats the player, before the player gets to fight Onyx again.
