Within the facility that did not officially exist, staffed by individuals who were supposedly dead, there was an archway. It was one of many artefacts that were housed in this facility, and was currently under the watchful eye of various scientists.
These scientists did not have names, as they were classed as dead. All they had on their lab coats was numbers.
The archway in question had been put to the side. The research for it had simply run its course. There were only so many times you could splash various chemicals and acids onto a material to see how it reacts, and get nothing in return.
Linguistics had proven useless, as the language was simply incomprehensible. They thought they had deciphered the language on the archway for a while, but when they tried translating a few parts it came back as gibberish.
They couldn't even power the anomaly to see what it did. It was completely impossible, or so they thought. Until one day, it simply powered itself.
