Mortwake's Tower (previously named "Klaven's Tower"), named after its previous rogue Defias master Klaven Mortwake, lies at the southeastern edge of Westfall near the river and north of the Dagger Hills. It seems to have been taken over by the goblin, Helix Gearbreaker. The SI:7 has been scouting this tower for some time and sometimes seeks help from adventurous rogues to sneak in and gather intelligence.
