Atalika gives you a feral attraction beacon to place within the Thexian camp. This will attract the bear he is working on and take care of the Thexians.
The beacon has a cast time and will break your invis or stealth; it can be placed behind the tents with some caution. A short time after it is set the bear comes and rips through the Thexians like honeycomb.
After you complete the task see Malyl N'Vazin at the Wanderlust Fair.
