Its a joke item you can sell for the money. I assume its an inside joke to one of the devs.
...based on the complaints about the poor return on selling to merchants. Your one-stop rich item.
Actually, I'd have no problem with the amount we get now for selling items, if only it was a higher cost percentage of the actual base price. In other words, lower the actual value, don't raise the percentage on the return for selling to merchants.
Or keep it as it is, and provide buildings that improve that percentage. Which, I suspect, is one thing we might see in beta 4.
