Dark Elf faction questions

[paladin1118]

I'm thinking about making a dark elf wizard... and I would eventually want to take the character to crushbone. The problem I foresee with this though, is the faction hits with indigo brotherhood for killing CB orcs. Indigo brotherhood is the dark elf guard faction, right? So that would eventually make me KoS in Neriak? And at all dark elf outposts?

If I ended up kos in Neriak, is there another wizard trainer I could use somewhere? Maybe the evil wizard trainer in east freeport? Is there any indigo brotherhood faction guards in east freeport?

Also, about how many CB orcs would it take to make a dark elf non-kos to kelethin guards? I'm assuming, even if I'm able to raise the kelethin guard faction to dubious, the kelethin merchants and banker still won't talk to me, since they're probably on a different faction? If I end up kos to Neriak would I basically be cut off from all bankers then?

If I can make the dark elf agnostic, would that help with faction at all?

I realize doing something like this would probably be very difficult. I'm just trying to find out how difficult, I guess.

Advice and answers to my questions would be appreciated, thanks.
