Maul is the chosen "Black Hand" of the lord and founder of the Burning Legion, Sargeras. He is also the founder of the cult Malevolence. He is responsible for corrupting the Warchief Garrosh Hellscream. "Maul" means "Doomspeaker" in Kaldorei tongue.
"Maul" was once known as the famous Varo'then, Captain of Queen Azshara's personal guard, and her chief advisor. He mainly led her forces during the War of the Ancients and considered as her most loyal aswell as trusted servant. He was believed to be "dead" after his fight with Malfurion Stormrage, but suffered horrific injuries from the battle that left in vegetative state. AFter over a year of being in a coma, Varo'then awoke and desired revenge on the Kaldorei people and all of Azeroth. He performed some of the ritual that allowed him to contact the Nether, and he was teleported there. Face to face with the lord of the Burning Legion, Varo'then submitted to Sargeras and the demon re-named him as "Maul" - His Black Hand. For over 10,000 years, Maul remained at the Nether and the demonic energies slowed twisted him into his current form. He was trained personally by Sargeras and the Dark lord transferred a portion of the Dark Titan's power to Maul and through this, Maul gained a tremendous amount of power that made him highly resistant to magical attacks, immune to fire attacks, and Sargeras even taught him Telepathy, Illusion and other abilities. Maul has his own double bladed sword, which he crafted him and called it as a "lightsaber". He returned to the mortal world and was responsible for twisting Garrosh Hellscream by transferring Sargeras's spirit to Garrosh, making Garrosh a vessel to the Dark Lord. Maul has recently been sent to assasinate Varian Vrynn, and launched a siege on Stormwind, with Satyr lackies.
Mauls controls a large number of Satyrs.
