Quests for evil races

[Fettsack]

Hiya,

I was wondering how some iksars can bank in freeport. Must be a quest I guess to raise your faction...?

Is that possible with let's say an oger, as well?

And what can I do to raise Highkeep faction as evil race? Killing the shralok orcs, right?

Greetings,
Fettsack
