A comment in the Mining thread made me remember an idea I've had for the longest time, and one that I pretend is an actual mechanic IC already ( @Jurixe
knows this more than anyone). What I propose is simple enough. Add a denizen office into the Isle of Delos, or even just a denizen in the Delosian Bank, that functions as follows -
GIVE 5000 GOLD TO <denizen>
<denizen> nods, taking a thick inventory ledger from a drawer in his desk.
<denizen> says to you, "Alright, hand over what we're taking custody of, and we'll provide the necessary paperwork. Nod to me when you're done."
GIVE <items/gold> TO <denizen>
<denizen> pens a quick note on a certificate of fine stationery. After using an embossing press to stamp his seal into the corner, he hands it back to you.
<denizen> says to you, "Here you are. Simply direct the intended recipient of that lot of goods to bring this note to me here, and we'll hand everything over. A pleasure to provide our services, as always."
I think it'd be great for all sorts of things, from prizes in City/House competitions to business people handing over goods. I don't think it should function as a non-decay room for people, so at most I think anything in custody of the promissory office should be treated as being in stasis, a maximum of ten items, and only a maximum of five (5) notes requested by any one person at a time. Regarding commodities, herbs/minerals and gold, however, should be fine enough to keep for these purposes. Selling people the commodities for a room credit, for example.
