The Locks were a gang from the Chokes, identified by their bright green topknots. They were hired by Acher to kill the party and retrieve the mouldstone casket. Their first attempt failed and they subcontracted the hit to the Waydon Crew, who fared no better. The party went to speak to Thrassa, the leader of the Locks, who granted them an audience under the orders of Katya. During the meeting, the Locks’ headquarters was attacked by minions of Acher using Sil’ess weaponry, supported by the Sirens. The party took them out, but not before the Locks had been decimated and the headquarters destroyed. Only Thrassa survived.
