FP Banker- What faction?!

[Chucck]

Does anyone actually know what faction the Banker in NFP is actually on? I am an Agnostic DE Mage. I was always able to bank in there until one night I killed something(no clue what, was in high pass keep) months ago and have been KOS to the JUST the banker ever since. The guards con me as Amiable, the Girl in the bank is Dubious, shop keeps non KOS, but the Banker himself is threatening. Would love to fix this somehow.
