Description from the game's inlay.
Loki the God of Lies has tricked Jorund, King of the Northern Vikings into entering the forbidden Garden of the Norns. The other Gods, enraged by this insult have imprisoned him in the Kingdom of Lukx. Jorund's Daughter, Hundra has convinced the Gods that it was all loki's fault but she hasn't persuaded them to free her father. But they have given Hundra permission to attempt to rescue him.
This is a difficult task! Hundra has to get into Lukx, free Jorund and find the three sacred jewels before she can get out again.
