King Arthur and the Knights of Justice

Arthur must travel alone to Castle Morgana to save Guinevere and two of his imprisoned Knights (Lancelot and Trunk). Infiltrating the castle appears to be simple enough, but will he escape with his goals accomplished?

After welcoming a fleeing peasant into the sanctuary of Camelot, the peasant reveals to Arthur the location of one of the Keys of Truth which is known to reside within a church in the village of Wellton. However, Lady Elaine warns Arthur and his Knights of a premonition she recently has dreamt, foretelling the quest to gain the Key of Truth to be a trap.

Arthur has learned the location of one of the Keys of Truth - His own. Though getting out of Camelot to get the Key proves difficult, with the Warlord's blockade forcing Arthur and a small group of Knights to use Merlin's magical underground tunnel. Merlin is unaware that Morgana Le Faye uses her magic to discover exactly what the Knights of Justice are up to and so sets a trap near the tunnel's exit. Can this trap be sprung?
