"If you can leave your flat land thinking and think of many surfaces, one over the other, extending on and on under the water as well as under the land, you begin to understand. But you can’t really comprehend immensity, can’t comprehend a pioneer job that has been going on for hundreds and hundreds of years and is still only beginning."
- Richard Sharpe Shaver
Not all subterranean spaces exist wholly in this reality. The upper regions may be near mundane, and just beyond that merely stocked with the detritus of the visitor's own unconscious, but the deeper regions, the outer regions, bleed into the cosmic. These are the places that few venture purposely, but some freak pyschonauts do, risking sanity, body, and perhaps soul, for an elusive apotheosis.
One has to be prepared, of course. The delvers rely on protocols self-published and passed around by fringe theorists and weirdos. They hunt for cryptic hints in Forteana and pulp science fiction. The details are various, but in all regimens there must be some development of the avatar, the psychic projection of self that can slip from the mundane to the other realms. The avatars are themselves archetypes from the Jungian depths, ready for the hero's journey. Is your inner self Wizard or Warrior?
For the act of slipping itself, well, there's the chemical trigger.
For the act of slipping itself, well, there's the chemical trigger.
The underworld isn't empty. It's populated by monsters to wound and frighten the delvers, and scattered with treasures to tempt them. Both the horrors and wonders are distractions to the true adept, though more than a few have contented themselves with some bauble from dream or nightmare, and an unbelievable story to tell.
The true seeker, however, keeps going. Down, down, down. And beyond.
