I would LOVE a bank in murk or dreadlands. Murk already has a vendor, which sells some food and drink, he's right next to the ramp. Refuge also kind of does, but it's the spell vendor, so there's no way of getting food or drink from there (or other neat items maybe, since murk has food/drink?)
There's even good spots to put the banks. In refuge, there's a pyramid with storage containers under it, which would be a great spot for a banker. In murk, there's a food storage area, so either in that building or the building next to it would be a good spot to put the bank.
This is really one of the most annoying things about ikisith, is that there's no bank. Hopefully one gets put in one (or preferably both) zones!
