Draft of my second SCP. Needs peer review!

Greetings everyone. Around this time last year I wrote and posted SCP-2429 and it was my first successful SCP article! I'm very happy about that.

I decided it was time to try another one and I'm enjoying the idea.

Here's a link to my sandbox: http://scpsandbox2.wikidot.com/secain

It is under the "SCP-XXXX WIP" tab.

It's quite long and possibly very confusing so I'd like some feedback and opinion. Maybe the length is perfect or maybe it could be cut down some. Or hey, maybe it's missing something.

Feedback and critique are very welcome.
