Mal'Ganis is one of the Nathrezim, or dreadlords, who served as the Lich King's elite jailers. He aided the Lich King in his task of preparing Azeroth for the Burning Legion's second invasion, spreading a plague through Lordaeron that would turn the population into mindless undead. Posing as the leader of the Scourge, he confronted Prince Arthas at Stratholme, and watched him purge the city before its citizens could turn. Impressed by Arthas' resolve, Mal'Ganis goaded the prince into following him to Northrend. In a desperate attempt to defeat Mal'Ganis, Arthas sought and found the runeblade Frostmourne. However, this was Mal'Ganis' plan all along, as Arthas forfeited his soul to the Lich King when he claimed the weapon. When Arthas finally confronted Mal'Ganis with Frostmourne in hand, Ner'zhul betrayed his jailer and commanded Arthas to slay the dreadlord.
Mal'Ganis, being a demon, wasn't killed and his soul merely returned to the Twisting Nether. After reforming his body, he returned to Northrend, where he manipulated the Scarlet Onslaught - an elite branch of the Scarlet Crusade - in the form of Barean Westwind. When his cover was blown, Mal'Ganis retreated, but eventually came back when the Legion invaded Azeroth for the third time.
