You were an anomaly (describe your powers as you wish) that just...existed. Until the SCP Foundation discovered and detained you, placing you in your holding cell. You've been examined by researchers and foundation scientists, trying to make contact, You were a mystery to them, you're not aggressive but you don't show passivity either, and your abilities aren't known yet. All in all this foundation was fun!...or was it just you? (you can start the action however you want)
