Following the Thread is a main quest in Act III of The Witcher that drags Geralt from Vizima’s Temple Quarter down into the sewers. It starts at the end of A Posh Reception, when Declan Leuvaarden tells Geralt that Salamandra funds itself by selling fisstech and runs a production base somewhere in the Temple Quarter. He points Geralt to the jailer Jethro, who knows the local trade better than anyone.
Jethro sends Geralt to the dealer Angus, whose letter of recommendation is the ticket into the Salamandra drug lab beneath the city. Inside, Geralt finds a letter from Gellert Bleinheim, commander of a Salamandra cell, and fights his way out to where the city guard is waiting. Handing the letter to Jethro wraps things up and kicks off The Viziman Connection.
