Mephisto, the Lord of Hatred is the eldest of the Prime Evils. He is brother of Diablo and Baal and deals primarily with Undead creations.

Background

Mephisto is known to be father of two demons: Lucion and Lilith. Mephisto's daughter was the lover of the rebel angel Inarius, and together created Sanctuary. Both of Mephisto's children had a big responsibility behind the events of the Sin War.

At the end of the Sin War, the Angiris Council dictated judgment against Angel Inarius, Sanctuary and his abominations: the nephalem and the edyrem (children of the mating between rebel angels and demons. Mephisto's shadow appeared before the Angiris Council proposing a truce and a pact.

Mephisto offered to let Sanctuary be untouched by either angel or demon to see what the children may yet become on their own for good or ill.

"We, like you, made false assumptions about this place, false assumptions about the creatures spawned by both our kind. But Sanctuary is much more than we envisioned! And we will let it grow and see where it leads, good or ill, untouched by either side."

The Angiris Council didn't believe the word of a Lord Demon. However, Archangel Tyrael stepped forward and asked Mephisto if he was truly proposing a truce, in order to believe him, he had to cast his mark on a place of Tyrael's choosing. To this Mephisto agreed, with the condition he was given a prize for such a goodwill gesture.

Archangel Imperius nodded at Tyrael, in agreement to Mephisto's petition. Mephisto requested the Angiris Council to be given the rebel Angel Inarius to pay for the loss of his children: Lilith and Lucion; and the sealing of the truce.

The Angiris Council, Mephisto and the three Sanctuary residents (Mendeln, Serenthia and Rathma) shifted location instantly. No longer were they at the Silver City, but on the vicinity of the Cathedral of Light. Tyrael signaled Mephisto to place his mark upon the point where the rebel Angel Inarius had preached to the masses of Sanctuary for centuries.

Mephisto rose his hand and bit it to bleed his black fluids upon the place chosen by Tyrael. Afterwards, Inarius was given to Mephisto to be taken into the Burning Hells for eternity. Mephisto asked what would be done with the cavern and the find within -- referring to the Worldstone. Archangel Imperius said a new pact should be done about that. What this pact was is yet unknown. Mephisto agreed with Imperius that the edyrem were to begin at the beginning with their powers set dormant and their memories of the past events of the Sin War to be wiped from their mind. Mephisto requested the firstborn, Rathma and the other nephalem to be able to remember for they were few remaining and their day was at an end.

Rumors

Mephisto in Diablo II.

• It is not confirmed, but it is thought that Archangel Auriel and Mephisto might have been lovers due to a remark and a wink hurled in Auriel's direction after Mephisto said:

"... false assumptions about the creatures spawned by both our kinds." - A blazing red eye materialized, then winked in the direction of Auriel, who utterly ignored it.
