Prishum's Revenge: The Battle for the Underground City
Paul Duncan, author
Every random number of years, the Legions of Marduk march down from the Frozen North to pillage the towns and villages of the continent of Euratwin. The few feudal kingdoms that dare to stand against them are crushed under the merciless feet of the Legions . One child on a small medieval farm is made an orphan by two cavalrymen of the Legions, and flees the country with a small group of refugees. Swearing vengeance upon the cavalrymen who killed his parents, he has to break the tradition of his peaceful ancestors and become an assassin, to have a chance of exacting his revenge on them.
