While renovating the ruins of the Castle Keep to suit their needs, the trio are interrupted by a wild boar's attack. Valiant tracks the wounded animal and falls into some underground caves inhabited by an insane old Viking named Tor. Rowanne and Arn venture into the caves to save Valiant from Tor's death traps; for some reason Arn's behavior grows increasingly irratic. Can our heroes survive long enough to learn why this aged Viking is waging war on them?
