So, can anybody tell me to coordinates to go to to trigger the fight? I've explored all around lake tohtle, and I've only ever encountered screamers, lindwurms, and those weird pig things.
Check the quest log in your journal and click the "Map" button on the journal page. It will auto open your map and pinpoint the exact spot you need to go to.
I don't think you need to finish the the L15/16 Storyline quest all the way to choosing the NPC companion to flag this quest. I was able to flag it before selecting a companion (although the main L15 storyline quest was complete).
