Jourrael

 is a nightmarish specter, an ancient assassin of Lolth, the Spider Queen. As an NPC, is played by Matthew Mercer.

Appearance
Jourrael has the appearance of a red-haired drow woman, and has a spectral form.

Background
Referred to as the Caedogeist, Jourrael was a chosen assassin of Lolth, the Spider Queen, exalted through an arrangement with Asmodeus during a brief era of unified interests. Jourrael was a nightmarish specter who walked through walls and mountains like water. Known colloquially as the Inevitable End, Jourrael could not be completely destroyed unless the contract of the agreement between Lolth and Asmodeus was destroyed. In the bloodshed at the end of The Calamity, this attempt failed, so the body of Jourrael was sundered and sealed apart in secret. The heart was buried within the Lotusden Greenwood, and the skull entrusted to the elves in the Veluthil.

The party meets up with Caleb at the Invulnerable Vagrant, where Pumat Sol tells them his stock is low because he's been busy producing requisitioned wartime supplies for the Assembly. He asks them to get him a vial of Swavain basilisk oil, and they agree. They also purchase several healing potions and a potion of maximum arcane power. Suddenly, Caduceus feels a searing pain in his back as he is attacked and seriously wounded by a red-haired female drow specter that immediately shifts back into the ground like a ghost.

Trivia

 * The title Caedogeist likely comes from a combination of Latin and German, which would closely translate to "Slaughter Ghost."
