Sadda, also known as Sarda, is a sage in the original Final Fantasy. He lives in the Sage's Cave southwest of Melmond. To reach the cave, the Warriors of Light must pass through the Giant's Cave, which requires retrieving the Star Ruby from the Cavern of Earth. Once the heroes reach him, Sadda will tell them that the cause of the earth's rot lies deeper within the Cavern of Earth and relinquishes the Earth Rod to allow them to go farther down.
Sarda appears in 8-Bit Theater (using a modified sprite of Doga from Final Fantasy III) as the character who sends the Light Warriors on the quest for the Orbs, though he is highly antagonistic towards them and insults and tortures them frequently. He has god-like powers and later becomes a main antagonist.
