This popped up for my in Azsuna, just north of Felblaze Ingress, But when I try to run to the location, it arrow just spins around and the quest never engages.
I kept running around, finally got it to pop after circling a tree on the road. lol.
Kill and skin Sunrunners in the area.
Kill the pretty unicorns, yay.
Kill the pretty unicorns yay.
As the map above shows, the in-game marker of the world quest is slightly wrong. You just need to head North East slightly and you will get the quest.
This quest may be bugged. I killed a few dozen with no luck, then I got a group of 8 together and they all had the glowing ring under them, unlike the others. I got all 12 drops from one group after skinning.
