Tile roof I'd bet is either 2 ancient bark, or 1 ancient bark and 1 corewood. Though I'm not ruling out that's it's 2 darkwood, something we'll harvest from the ancient roots that are active but not intractable in the Mistlands.

Log bench will probably just be what we already see in Fuling camps, so corewood.

Cooking utensils may be either iron or tin, with butcher being iron and finewood. Would be kinda fun though if the butcher bock needed a copper knife instead of just a bar of metal.

I'm also betting we'll see slanted corewood beams and maybe iron beams as well. Onion seeds I'm thinking may be in the meadows, since forest, swamp, and plains already have crops in them.
