After several months of constant survey, on December XX, 19XX the being created what we believe to be a writing implement and a sort of paper. Began to write continuously and ended after two weeks of observed writing. After having completed what it was doing, subject slipped it's paper under the door. Paper was found to be the schematics for an Anti-Material weapon using current technology. Weapon is still being developed, though progress is being made, and strangely enough, at the same pace as the being had calculated. Some of the researchers have begun to call it "Tesla", after the physicist Nikola Tesla. hat these observations reveal is 1. The being is highly aware of it's surroundings and current time. 2. the being is highly intelligent, it's power is not innately used, but something it can control. 3. The being is held willingly; the creature could have escaped long ago if it was able to destroy matter, or at least compress it (as was observed during the initial observations).
June XX,20XX - Subject has given man blueprints since the first one back in 19XX. It is obvious how dangerous this being has become. Not only for it's power, but for it's intelligence and willingness to give out information on destructively weaponry. All blueprints after 02X are to be incinerated by Class D personnel and then executed. We've yet to discover if it is neutral or our friend, but one thing remains certain - if any of our enemies were to get their hand on SCP-XXX, humanity would be put in grave danger.
