The Universal Gates

The Universal Gates are massive gates that transport the entering creature into another reality/universe. They were discovered about way back in 1874 AD, when Frankish, government officials found a strange creature who appeared out of nowhere. It was discovered that the creature came from another universe/dimension. The Frankish government kept the whole situation classified.

During the Khanzem period, Whoot had his spies infiltrate a Frankish government base, which held all the documents and files about The Universal Gates. Whoot was planning to travel to a primitive universe, and enslave the creatures to use as slaves. He was stopped by the BoF however, but everything that took place was kept secret from the community.

In 1990 the BoF took over all operations concerning The Universal Gates, but did little about them. The Gates were finally found near Jupiter, in 2004. The BoF built a small base there, that workers can live in for about two months. Since then the Gates have only been slightly studied, and have hardly been touched.

Description
Each Universal Gate is a machine, which opens a portal to another dimension/reality/universe. Scientist have examined the Gates very well, and they are definitely created by intelligent creature(s). Historians and scientist alike are trying to find any type of evidence of the Gates in historical records, because the Gates are not natural. The portals that the Gates open are all different colors, and are powered by some Wutt Energy emitting from the Gates. On the edges of the Gates there are some things to give clues of what that reality is like.

Trivia
