Tunnel under construction

The term Tok'ra tunnel refers to the underground bases and the networked crystalline tunnels by which the Tok'ra conceal themselves from the Goa'uld.

Overview

When the Tok'ra arrive at a new planet, they immediately move beneath the surface and grow special crystals which bore through the ground, forming tunnels hidden from the Goa'uld. These tunnels do not typically have an entrance or exit shaft to the surface, but instead use Transportation rings. There may or may not be more than one transport ring system in a Tok'ra base. Life support is required but not immediately because as the crystals tunnel through certain materials, oxygen is produced as a by-product. This gives the Tok'ra time to set up air-scrubbers and other life support systems.Different shapes and sizes of crystals produce different kinds of tunnels; some long and straight, some leading upward or downward, some creating open rooms. (SG1: "Last Stand")The tunnels are also capable of deconstructing themselves by command. The deconstruction process is particularly hazardous.
