Realm of Dreams Quest/Spoiler

Requirements

 * Chayenne's Magical Key (not destroyed upon entering)

Method
A book found on Draconia contains a poem alluding to this quest: Guarded by fire and dark walls, a long forgotten secret lies. Never meant to be opened, yet now it awakes. Key to magic, wielded as a sword by those who fought. The first and the last tease, creation and destruction.

In Ankrahmun's dragon lair, there are magic walls and a pressed down switch tile covered with fire.
 * Questers report being able to make the switch tile pop up by using destroy field on the tile. This doesn't always work, it may be dependent upon something else or just random.
 * The switch tile supposedly removes the stone pile north of it, under which is a lever to destroy the magic walls.

Research
The poem is probably the only clue available in solving this quest. 1. Guarded by fire and dark walls, a long forgotten secret lies. 2. Never meant to be opened, yet now it awakes. 3. Key to magic, wielded as a sword by those who fought. 4. The first and the last tease, creation and destruction. Interestingly, some research notes are found around Ankrahmun's library which may be related (but they were implemented before the quest): Researchpaper 77-04 D The 'move earth' spell seems to be ready to enter the stage of field testing. The results so far were quite convincing, and the priests were pleased. The recent studies we have carried out together have proven that we can indeed learn from each other. I must admit I would certainly like to add this useful little spell to my personal repertoire. After all, shovels and pickaxes are heavy and pretty unwieldy, and I would very much like to leave them at home. I envy the priests for the elemental powers they are wielding.
 * Line 1 probably refers to the Ankrahmun dragon lair, with daily spawns of fire and magic walls.
 * Line 2 may refer to the dream realm in part.
 * Line 4 ("creation and destruction") probably refers to the destruction of the stone pile and/or magic wall.
