At the behest of his lord and as part of his basic necromantic practices, Mannimarco frequently rounds up citizens to be sacrificed, removes their souls from their bodies and pledges them to Molag Bal, sending them to Coldharbour. While Mannimarco plays at manipulating the Imperial Empire from behind the scenes Molag Bal is far less concerned with physical rule and far more concerned with sending souls from Nirn to Coldharbour.

In the game Molag Bal, acting through his supplicant, Mannimarco, conspires to con the rulers of Cyrodiil into destroying the Amulet of Kings, thus breaking their compact with the Divines to keep Oblivion and Nirn separate and allowing Molag Bal to begin formal conquest of the world, theft and domination of the souls of men. The Elder Scrolls Online, the prequel to the entire series, features Molag Bal as the main antagonist. Then, has the player kidnap a priest of Boethiah, a rival Daedric Prince, and force him to restore the Mace of Molag Bal, which he desecrated, before killing him. First, his voice takes hold of both the player and another man, a Vigilant of Stendarr who is venturing into the house with them, forcing the player to kill him. His quest in Skyrim involves an abandoned building which was built over his shrine. Petilius was a local hero who gave up violence forever when his wife died, and Molag Bal wants the player to provoke him into killing them (he “saves” you when this happens so you don’t actually die) with a cursed mace by attacking Petilius while he is praying at his wife’s grave, thereby damning his soul.

In Oblivion, his quest involves Melus Petilius, a man who disgusts Molag Bal because he is such a good person.

When they are killed they are both banished to Molag Bal’s realm to be punished for eternity. In Morrowind, Molag Bal is the only one who can cure the player if they become a vampire and will only do this for them if they first kill his daughter, a demon called Molag Grunda, who he hates because she is in love with a Frost Atronach named Nomeg Gwai.
