Ardebaran (アルデバラン Arudebaran?) is the first enemy from Tecmo's Deception: Invitation to Darkness. He was the master of the Castle of the Damned, a masked man with a sword that attacks anyone who enters his domain and is said to abuse his power as a covenant.


In his quest for power, the Prince of Zemekia went to the castle and stumbled upon Ardebaran alongside a soldier. The soldier was killed by Ardebaran, but the prince was rescued by Idorigo. Later, the prince avoided a trap set by Ardebaran and caught him with a Volt Cage set up by Astarte. After killing Ardebaran, the prince became the new Castle Master and obtained his dark powers.
