How to get good faction with iksars?

[Varsha]

Im a dark elf cleric. My brother rolled Iksar SK. I was crazy enough to run though Overthere at lvl 5 and wait till lvl 12 to bind near Kesora. Im glad hes nice and vendoring all the trash for me. But I would like to work on the faction so I can go in to sell on my own and bank etc.

So - is there any way to raise the faction with iksars without losing faction with my own people?
