Need some Magic Tattoo thoughts
A barbarian HAD a tattoo of a map on his back. This tattoo was given to him while he was in a drunken stupor by the Kenedhel, a people well schooled in witchcraft. The map tattoo was intended to bring the barbarian to the homeland of the Kenedhel to fight some bad guys for them. The barbarian did so, earning their respect and friendship. The Kenedhel have worked over the old map tattoo into a new tattoo, with some kind of (probably minor) magical properties.
Question: What does this new tattoo do?
