This is quest 2 of the original quests.

"Sir Ragnar, one of the Emperor's most powerful knights, has been captured. There is reason to believe that he is being held prisoner by Ulag, the Orc Warlord. You are to find Sir Ragnar and bring him back to the stairway. Prince Magnus will pay 240 gold coins to be divided among the Heroes, if they rescue Sir Ragnar. No reward will be paid if Sir Ragnar is killed during the escape." — Mentor
