To be a normal man at last, Thorgal will have to storm no less than the Invisible Fortress.

Still travelling with Kris of Valnor, Thorgal runs afoul of a local tribe. When a mysterious old woman offers him a chance to escape the hostile villagers, he accepts. But there's more to the bargain: She says that if he can make his way into the Invisible Fortress, he'll be able to erase his name from the Stone of the Gods, cancelling his destiny-and finally have a chance at a normal life.
