Mazurka, ruled by Hecate, is the fourth dungeon to be traversed in the game. It is divided into 2 towers: west and east. The dungeon is initially entered from the 1st floor of the west tower, and after climbing to the 8th floor will connect to the top of the east tower. The 6th floor of the east tower is Mazurka Corridor's town with a shop.
A thief named Gaia stole the Silver Relief from Hecate, which angered her due to it being her most prized possession. If Nakajima finds Gaia on the 8th floor dark area, he'll have to pay him all of his Macca if he wants the Relief. A statue of a goddess found in the corridor will teleport the heroes to Bien's second floor. On the 5th floor in the east tower is the statue of Latos on a pedestal, rigged with a trap. If Nakajima doesn't have the Jewel of Heaven or Ares' Necklace to replace the statue with, the party will take an extreme amount of damage. Soon after the Silver Relief is used to open up a passage, Nakajima encounters Hecate, who is initially invisible. The magic power of the statue of Latos deactivates her invisibility, however. After Hecate's death, the Orb of Resolve is found.
In the remake Kyuuyaku Megami Tensei, a wounded man can be found, begging for a weapon. No matter what decision is made, he'll reveal himself to be a demon and battles the party.
