The main antagonist of the Maple world. The Black Mage is the one who threatened the world before the time of Altair Camp who was defeated by Aran, Freed, Mercedes, Phantom, and Luminous. He killed Freed and sealed off Aran, Afrien (Freed's Dragon) the other heroes for hundreds of years. Later Empress Cygnus started a new group of knights to assist in defending the world.
He would most likely become an extremely powerful monster, possibly even the strongest monster in the game. He owns a unknown fearsome Onyx Dragon (not Afrien), which is presumably very powerful as well. He is heavily involved in the plot of the Arans, Evans, and Explorers, partly because many of the quests involve fighting the monsters that are under his control.
- The Black Mage was raised in his hometown, Edelstein. Later, he went to Magatia to study alchemy. MapleWorld was chaotic at the time he studied alchemy, and believed that people can't be trusted making their own decisions and believed that there needs to be a king controlling their lives.
- He rose in power and took over Ossyria, causing a group of explorers to flee Ossyria. He joined forces with Ephenia, queen of the fairies and they both poisoned Ellin Forest.

- The five heroes of Maplestory had defeated the Black Mage, but not before he placed a curse on each of them which sealed them all for a very long time.
- Von Leon signed alligance to the Black Mage, after his wife was murdered on the night the Cygnus Knights marched into El Nath, after they got reports saying that he signed alligance to the Black Mage. After the Cygnus Knights "pushed him back to his castle", he signed alligance to the Black Mage, which gave Von Leon the ability to gain vengeance. As a result, the people of El Nath suffered from a mutation that changed them into animal demons.
- The Black Mage's minions, the Black Wings, resurrected their leader. This caused cataclysm, changing all of MapleStory into a void of Darkness.
