Right, each hero has their own specialty:
The Rogue produces wood at the Workshop.
The Caster can create material stone at the Atelier.
The Warrior uses materials to fortify weapons and equipment at the Forge.
The Archer tends to the livestock and collects their byproducts in the Fields.
The Farmer grows crops on the Farm.
The Fighter cooks dishes in the Kitchen with ingredients from the Farm and Fields.
And the Wanderer can swap places with the others to take over any facility as needed.
These are the only facilities available, and the game has no town-building elements.

Every hero except the Wanderer manages a facility that takes advantage of their unique skills.

Before you explore the Abyss, you can ask anyone to produce something for you while you're gone.
If you want turnips, for example, ask the Farmer to grow them. Or if you want milk from the cows, you can ask the Archer.
By the way, if you want to explore the Abyss with the Farmer or Archer, no worries! The multi-talented Wanderer can take over their jobs.

You can then use these materials for forging or cooking. With the right items, you can even instantly complete certain requests.

So you're essentially describing...a cuddle puddle?

No, they prefer to haunt its dark depths.
The Princess's presence at the edge of the Abyss probably prevents them from escaping.
