Playing as Maya I got the cue from the Warrior guy to look for Jadeen, and could find her and start the quest. Jadeen always ran to the wrong place though, and stayed there only telling the player to be quiet. I tried again as Max, and found Jadeen went to the right place, but would'nt attack raptors. The only way I could complete the quest was to be Max and kill the 6 raptors before talking to Jadeen.
I think the initial hint about Jadeen should be given to Max and not Maya, or if Maya is supposed to be able to complete the quest then it's just broken.
The carrier drone for Gulhragg can be bypassed by speaking to Lyndon again, who will send you back to Gulhragg to complete the quest.
I haven't come across Market rivalry or bridge lights, yet. Still got some exploring to do
