Halfling.
I think Boxes 1 and 4, Decanter, Gem, Haversack, Kit, Biscuits, and Sticks can be all group property.
Ero will insist on the Grimoire and Pen but will allow other the magic users borrow them (even though they're barely literate), so we can consider them group.
The Curtains, Sheets, and Tool we can sell the next time we hit civilization.
The Tankard could be group but with only 3 charges a day, it won't go far. Better to sell it.
I presume the Dimension Windows on the tapestries are linked to each other, so we can keep one tapestry with us and set up the other in some town. That way we can just hop back and forth as needed.
Ero would prefer the Compendium over the Atlas, but if someone else wants the Compendium, I'm cool with it.
