The Changing Room

1. This is it. Read the following ONLY if you are completely defeated.
2. The Octagonal Maze is a three by three "square" of adjoining Octagonal Rooms.
3. You can go only through walls with silver runes, and only if the corresponding arm of the compass rose is silver. In other words, you can go in any direction only once. (See question "arms/silver/lead," clue 3, above.)
4. Within each room, any wall that borders another interior wall has a silver rune; each wall that faces out of the "square" has a lead rune. There are three exceptions: in the Central room, only the north, east, south and west runes are silver; in the Southeast room, the south wall is silver (since it leads back to the Carving Room); in the North room, the west rune is gold.
5. The Carving Room (or Maze Antechamber) leads you north to the Southeast room of the maze, transmutating the north arm of the compass rose. Therefore, you cannot go north again (see 3, above). The cube you seek is in the Northwest room of the maze. You can enter this room only from the North room (work out the logic for yourself). See the next question for how to cross that bridge.
6. There are four possible routes to the north room of the maze, all using the compass rose, of course: W, then NW, then NE. NW, then W, then NE. W, then NE, then NW. Actually, there are only three.
