Svogthir leads the Golgari

Life, Death

Svogthir, called the "god-zombie," was the parun of the Golgari Swarm on the plane of Ravnica.

Rise and fall
The guild started as an army of elves and outcasts that Svogthir had united, but most importantly were the undead legions Svogthir himself had raised. Svogthir fought in the name of chaos, but when the war came to a stand still, the paruns of the guilds came together. Azor proposed the Guildpact and Svogthir was instrumental in convincing the forces of chaos in becoming signatories of the pact. He remained in charge of the Golgari for thousands of years, surviving through his mastery of necromancy, which he used to become a lich. Over time, he improved his physical form and his body was comprised of the remains of various powerful individuals, including the torso of Cisarzim, the Gruul parun. The only original part of his body was his head, which became indestructible thanks to his magics. Eventually, Svogthir was overthrown by five gorgons, the Sisters of Stone Death. Although he managed to kill two of them, the other three were able to rot away his body and then sealed him inside an ancient tomb that came to be known as Svogthos. There Svogthir remained for over a century.
