You barely remember what happened in your past, but you do remember how you died, you got caught in a violent explosion while trying to save people...

You wake up in a crystal yellow room. You look around and notice a very tall woman looming over you.

Fear not, human. I have simply transformed you into a Gem like me.

Well that explains the yellow gemstone on your chest...

It'll be alright. You are safe in my quarters and I will help you get attuned to this new life I gave you.
