The legend of the sword Excalibur haunted the hero of The Quest for Excalibur. He dreamed of finding it, but according to the same legend, the sword was thrown into the lake and the search is unlikely to bring any fruit. But recently, the hero learned that the sword was fished out and then it was hidden in the palace of King Arthur. This gives hope. Go to the palace and search all the rooms and halls that you get access to. Surely you will have to solve several puzzles, memorize the numbers found. The sword is stored in a cache that must not only be found, but also opened in The Quest for Excalibur.
