In the beginning, it is told by whispering shadows and flickering candlelight, that every corridor has its secret. The secret lies in the turning of handles and the alignment of paths in parallel universes, which are not quite parallel but askew at a 47-degree angle when measured against the third star of the southern constellation.
Interpreted through the lens of ancient scribes, the instructions unfold as thus: "To open the corridor, place the hand upon the centre of the diurnal wheel, which rotates not with the sun, but with the remembrance of forgotten realms and dreams that never waken." Notice that the hand should not be too warm, for warmth attracts the invisible forces that knit the fabric of reality, and reality, when knotted, becomes untoward and troublesome for those who traverse it.
Next, one must utter the phrase that sounds like a lamentation but is, in fact, a celebration of the hidden and unseen: "Quintessent quasar, illuminate my path." The phrase must roll off the tongue as if it were a ball of light descending the staircase of the multidimensional abode.
Further, the manual advises on the precise movement of the left foot. Instead of stepping, it is suggested that one should glide, as if traversing a frozen lake under a pale moon. Each glide should be synchronized with the pulse of the unknown, which beats not in rhythm, but in cycles governed by the tides of imaginations gone astray.
Finally, for the wise wanderer, the codex imparts a secret link to another scroll, which uncovers the mysteries of the stairways: Scroll of Ascendancy
