Oppressor Gateway

An Oppressor Gateway was a device created by the species known in Oralian sector as the Oppressors. (🇸🇹)

Design
Gateways were circular in shape, and are usually found placed on a platform or in a wall. The size varies, but most are large enough for a person to walk through. While inactive, the gateway resembles a perfect ring, with a empty clear center that looks like the opening of a tunnel that does no exist. When actived, by pressing a button on one side, the gate would open to a kawoosh sound, revealing a swirling vortex in the center ring which resembles liquid magma.

The dark metal used in its construction was undefinable by Federation scanners.

Purpose
The original purpose behind the Gateways was lost when the Oppressors disappeared. However, many have speculated over what that purpose could be. Some primitive species who encountered them thought that they were doorways to other realms or different dimensions. Others thought that they were prisons, designed to trap dangerous individuals.

Encounters
In 2383, the crew of the USS Pioneer (NCC-1084) discovered a Gateway on the planet Yoth. ("The Forgotten Planet")
