Treasure and Spending it
At the start of the game, the Family races are scattered and broken to the point of having no real economy. I'll update this with rules once treasure comes into play (it will quickly) and spending it can increase your groups power, status, and goodies.
As far as magic items go, permanent magic items are a big deal. The knowledge of how to make them was lost to the Family races. They are going to be found as battle loot and delving finds. You can still craft one-use items like scrolls and potions, and I'll make up a realistic price list them if we get that far.
