Well, first I think we should come up with a list of items that could go there, at least a good preliminary amount, then multiply that by a reasonable scale factor.
For instance:
gemstones, animal parts used in quests (such as the fox fur pelt), utility items used in building (a park bench is a park bench), elemental ingredients for scripts (sulfur, coal, etc).
Another thing, make the area show up on lore as "this is commonly found" instead of "not of the mortal realm" and some such.
