Grigore is a resident of Burgh de Rott, a small town in southern Morytania.
He disappears after The Branches of Darkmeyer the day after Razvan goes missing. A missing person poster for him can be found on the eastern wall of the building north of the Burgh De Rott bank, which reads "Missing: Grigore - last seen eating a rat."
After the player completed River of Blood, Grigore and the other missing civilians will return to Burgh De Rott. The missing posters will also be taken down.
