Skull is an old, wooden currency from the dark ages. It was used by the rulers to pay
mercenaries to do things for them that were better kept hidden.
Skull was therefore not an official currency and could
only be used in certain locations where the mercenaries
were among themselves and had their own laws.
So if you dare to go further, you better have a few Skulls in your wallet.
