I got the mission from Yusam the druid to figure out what was wrong with the Elk tribe and why they've turned evil, and then the commander of the fort nearby asks me to kill their leader, Zorkan. When I got to the Elk base there was a guard who I could talk to, but as soon as I clicked on him he went hostile. I got inside and everyone else has been hostile and I haven't had the option to talk. I faced and killed Zorkan, but I figured there must be some peaceful way to complete the mission. So I looked up online help, and I've found a couple of pages that simply say I should talk to him. But I can't talk to him because he just immediately attacks me

Can anyone help me? I'd appreciate it, thanks.
