Route 2. Mages Overlook / Castle Wizard Room
There is a pit at I11 (on Level 6 - Labyrinth I) which drops you to I11 (on Level 7 - Labyrinth II) at the so-called Mages Overlook where, we're told, Mages found the plateau useful for looking out over the labyrinth denizens following the great cataclysm. Making your way to K10 will lead you to a one way tunnel which will take you back to Level 6 - Labyrinth I, arriving at K10. But we're going to the door at M16. This is marked with runes which tell you that runes can be the most powerful of weapons in the hands of an adept wizard. Here the runes also protect the great mage's magical possessions against the unwanted. Going through the door will take you to Level 7 - Castle Wizard Room.
A gate leads back to Labyrinth II at M1. This area is a real swine! There are many walls with runes on them. These translate to words like Druid, Ethereal and Nexus. Walking into the wall will teleport you, sometimes to another area with more rune-covered walls, sometimes to a location in the main area that you could already get to and which has monsters in it or between you and the exit!
You will be told that those which haunt the castle must be spelled to find their master - list the rune words and the initial letters of some routes spell names of monsters and important characters. For instance:
You'll also learn from a scroll that to gain access to Arnakkian's chamber, you must defeat his lich apprentices. The third message obtained is, beyond the words lie the power of the earth. The master of this castle must be identified before the ghost may take you to him.
One you have done both the Arnakkian and En-Li-Kil routes, going to the door at I6 you are told that both Arnakkian and En-li-kil have been identified and the Ghost takes you to the Guardians. You are transported to Level 6 - Castle Parapets, K6.
