The gear rules (you can only what you can fit on your character sheet) don’t really work for an online game with a virtual character sheet. Plus they seem to invite silly games such as tiny writing and big heavy things with short names
So I’m going to adjudicate on a case-by-case basis but I need to know one thing: can/do mice (in the source material) wear backpacks? Or are they limited to things they can stuff in a cloak pocket or hang from a belt?
