Outside the Ramparts

In the first chapter: to reclaim the Dungeon that fell to the scheming William Delacour, the plan is simple: Marvin, Isis and Herbert must find some magic fugus purit and use it to dislodge the current occupants of the fortress. But is this really the Guardian's plan? Our heroes will have to fight against everyone to save the Dungeon. In the second: Herbert is officially mandated by Marvin to go see his mother and announce his engagement to Pirzuine. Upon arrival, he discovers her murder. Will the valiant duck succeed in finding the culprit before Marvin arrives, without alienating the village?
