Storrev

Storrev is an Devkarin elven lich and leader of the Erstwhile, a zombie faction within the Golgari Swarm of Ravnica.

History
Storrev is adept at the politics of court, and she is feared for her power to transform dead beasts into undead horrors. In the period leading up to the War of the Spark, the Golgari used the Erstwhile as servants. When Vraska came after the guildmaster Jarad vod Savo, Storrev turned tables on her master and joined Vraska's alliance.

As Mazirek was the one who had awakened the Erstwhile, none of them - even free-willed liches like Storrev - could disobey a direct order or refuse a question from him. However, when Mazirek formed an alliance with Nicol Bolas and betrayed Vraska, Storrev misled him and had him killed by a Rakdos Comedy Troupe.

Storrev remains an ally of Vraska, because the gorgon had freed the Erstwhile and had given them Mazirek, who had been their tormentor, to kill.
