Bronlor lightblade

[Roth]

So, I got an iksar shaman good faction with kaladim guards. I can do crushbone belt turn ins and I got my faction with the banker up to apprehensive. There's one problem: Bronlor Lightblade. I can invis past him, but to get to the quest guy without invis he always agros me and I'm dead. I can keep doing the quest with invis, but I would really like to be able to find a way to solve this issue without invisibility.

So I have two questions... is there a way to get around him without invisiblity or another trick, and secondly what faction is he on? If I knew his faction I would have an idea of how to fix it.
