To initiate passage through the Main Hallway, ensure that the label plaque reads "Not the End" at a 90-degree counterclockwise angle. Absorb the ambient echo ratio and align it with the frequency of door number XIII on the left wall. The right wall must be scrutinized for at least three minutes.
Activate ventilation through oral incantation of the true names inscribed on the ceiling beams (reference the 'unsolvable' glyph table for details). Ensure to hum in the frequency of 427 Hz at precisely twelve-second intervals. Double check the luminescence of the one-candle light source positioned in quarter four of the lefted quadrant.
Commence stairway traversal by recalibrating the orientation of the guide compass to magnetic north. Stairs corresponding to even numbers must be approached only under the full moon's phase unless documented otherwise. For stairs coded with prime numeric values, perform at least one circumferential loop at the midpoint hinge.
