Svogthir

Svogthir was the parun and guildmaster of the Golgari Swarm. He ruled the guild from before the signing of the Guildpact and remained in charge of it for thousands of years, surviving through his mastery of necromancy, which he used to become a lich lord. His body was comprised of various remains of powerful individuals, such as having the torso of Cisarzim, the Gruul parun. The only original part of his body was his head, which became indestructible. 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 his head inside Svogthos, the restless tomb. There Svogthir remained for over a century.

However, the parun reappeared at the time of the Decamillennial anniversary of the guildpact's signing due to the conniving of Savra, who wanted to use him to overthrow the Sisters of Stone Death. She freed Svogthir from his tomb and constructed a new body for him, which he used to defeat the Sisters, killing another two of them in the process. However, Savra then betrayed him, taking over the leadership of the guild herself by unsummoning his replacement body.

But Svogthir survived still. When Szadek betrayed and murdered Savra, Svogthir's spirit possessed the treacherous elf's corpse. He made an alliance with the Simic guildmaster Momir Vig and the two planned to wipe Ravnica clean using Project Kraj. However, Svogthir's mind was overpowered by that of Agrus Kos, who possessed Savra's body and used it to kill Vig. Svogthir's fate after this is unknown.
