Zetaz is the imp you first encountered when you first entered Mareth. You fight him here. You also get Soul Gem research here and automatically unbolt the door leading south from it. After you are done interrogating him you get Bimbo Liqueur and Zetaz’s Map which in turn opens up the way towards the final dungeon.
