Klaven's Tower
Klaven's Tower, named after its rogue Defias master Klaven Mortwake, lies at the southeastern edge of Westfall near the river and north of the Dagger Hills. SI:7 has been scouting this tower for some time and sometimes seeks help from adventurous rogues to sneak in and gather intelligence. It is a well known launching point for Defias activity such that it has also been called the "Defias Tower". Klaven's Tower is being used, along with Jerod's Landing in Elwynn Forest, in the smuggling of stolen goods from Redridge.[1]
Cataclysm
This section concerns content exclusive to Cataclysm.
In Cataclysm this tower gets renamed to Mortwake's Tower, most likely after it's new owner, now that the Defias are no more.
Patch changes
Patch 1.4.0 (2005-05-05): There is no longer a floating tree in Westfall above the defias tower.
