Banking in Kelethin for Evils

[rayeatts]

I was reading a thread about different trading zones from different servers back in the early days of live and someone mentioned that in Kelethin, evil characters can bank through some sort of window. I was curious if anyone could explain how this is done? As of now, I don't know where to bank when I'm playing my ogre or my iksar on the continent. I did discover you can use the druid vendors though.
