This area, found in The Big Mountains, opens up once you have the bridge in your inventory. It is populated by the horrid denizens of the Internet chat room, who will inflict bad spelling damage upon you. If your main stat isn't high enough, you will see the following message:
As you near the Valley, you hear the beating of drums. Sinister drums. Nearby sinister drums. You freak out, and can go no further.
The name "The Valley Beyond the Orc Chasm" is a play on a non-existent area in Zork 1. In the bundled "invisiClues", one could get help for Zork 1 with the use of a special pen that made hints appear below corresponding questions. The hints were divided by sections of the game, and one section was labeled "The Land Beyond the Chasm". The guide talks extensively about a bridge that can neither be found nor created, and, thus, the area is inaccessible. The section's purpose was to ensure that players couldn't spoil themselves by reading the questions and determining the answers; many other questions had no relevance to gameplay, and still others contained large amounts of blank space in order to fool a player into thinking that might be an important question.
