Guild Wars 2

Hello first post.

I was playing the vigil story line, and a few quests before Claw Island, the priory ally NPC showed up with the Vigil one, though all the cut scenes were with the vigil. At Claw Island they were both there, but it switch to the priory storyline and that NPC was killed. The next quest were the priory ones and not the vigil.

I have never played the vigil storyline, only been playing GW2 a couple months, is there any way to fix this?

First, welcome to Guild Wars 2!

Well, did you play Personal Story with someone else in their instance and accepted progress at the end?
