He Who Rules...
Excommunicated cleric of Kelemvor obsessed with alchemical undead.
Excommunicated from the Church of Kelemvor, Svilennius Tripe found a secret passageway into the Godsmouth Ossuary where he could practice his heretical obsession with creating alchemical undead. The Ossuary provided the perfect hiding spot and an abundant supply of corpses to revive.
His discovers and work were chronicles in a series of books known as the Chymists of Life in Death.
Svilennius was eventually killed by the Dreamless.
