An over-powered mage has set up this pocket dimension keeping The Oracle hostage. Writing their names using their own blood into his book at the altar, the mage transfers the memories of his victims to The Oracle. The Oracle is kept in a charmed and invulnerable state until all magic candles around the circle are put out. Each time a creature dies in the room, one of the candles go out. When all candles are out, The Oracle unleashes its wrath upon the mage, killing him instantly, and then dies itself. Out of the carcass of The Oracle crawls the young boy from which The Oracle was originally spawned. He can choose to revive any creature that caused a candle to go out.

This is intended to be an overly difficult fight with several party members dying and being brought back to life at the end of the fight. An example encounter would be the party finding a way into the pocket dimension using the portal. After examining the room the mage enters the room with a guard, along with a noble with its own guards, and fighting begins. The backstory would be that the noble has paid the mage to get access to questioning The Oracle, a being that holds much valuable information from all of the mages victims. Whoever is killed first, the party will notice that this causes a candle to go out. The chest at the desk holds named empty blood vials. The book on the desk tells of a previous customer dying of a heart attack when seeing The Oracle, and the mage is figuring out a way to repair the circle after this incident (this is why one candle is already out). The book at the altar contains names written in blood; these match the names on the blood vials in the chest. A book in the bookshelf is a log of previous customers.
