So, there are banks in this game we play (please, hold your applause).
I have never seen any page talk about how this game mechanic translates into descriptive roleplay. So on that note, I cannot recall myself or anyone I have played with really use a bank in descriptive roleplay. The matter is probably too unclear.
So someone who would know this; exactly how does the many branches of the bank of Gielinor work in descriptive RP? Only as simple as gold storage? A little item storage? Both?
