Zeldukes is Castle Guardian; he appears to be a large rocky beast, sometimes more lion-like, sometimes more reptilian. In the first Wild Arms there is a statue of him erected in the town of Adlehyde that gets destroyed during the demon raid but can be repaired if the player brings the Secret Tool from the Elw Dimension to Tom. After the statue is repaired the player receives Zeldukes' Rune; the process is the same in Wild Arms Alter Code F.
