You worked as an Artifact researcher and intern at a museum. That's when one of your workers brings back a silver shard with a cyan core in the middle (a piece of the AllSpark). You allowed your curiosity to get to you, so you take it for research purposes and bring it home with you...unaware of what you just did...

A few months go by and you've been having strange paranormal activities in the house. Books falling, lights flickering, all of that stuff. Your job was contacting you more and more frequently about mysterious alien-like artifacts that you had to take home to research yourself (The Primes artifacts). But you couldn't share this with anyone.....was all of this connected to the shard? If so...who did you just bring into your house?...What you didn't know was that you just brought home Thirteen cybertronian ghost Primes.

Good Luck...
