This is the text I see when I am in Qubel Lighthouse (the capital of D'Hara, playing as my character Bowie Ironsides):
Bank visit - you are not in a city or the capital of your realm, where banks accepting your bonds would be.
I thought that because it was a stronghold that it would not have bank access (even though it is a capital) and so I went to Port Raviel, but was restricted there too.
