Crystal's past

(We start again after Christine told how their mother died)

Me: So now you know... And I've been living with the guilt ever since...
Sprinklegirl2045: But it wasn't your fau-...
Me: You don't understand! If I would have seen Melori sooner, mom would have survived!
Crystal: Melori huh? That name sounds familiar.
Me: C- Crystal?! You were listening... weren't you?
Crystal: Yes I was... It isn't like you to storm away like that.
Me: Sorry I just... needed to be alone for a second.
Crystal: So tell me. We have encountered Melori again, right?
Me: Yes... Melori... is Shadow's father. (For those who don't know Shadow is Aurora's boyfriend)
When he found out that his son was dating my daughter... He wanted to kill Aurora. Shadow shielded her before I came and attacked Melori.... You were still bound to my necklace.
Crystal: I remember now.... You killed him... to avenge our mother.
Me: That was the first time I killed someone... But I had to...
CrossMayDay: Okay so we now know a part of Christine's past but what about you Crystal? Tell us about your past.
Crystal: I knew this was coming... Okay I'll tell you.

(Play the song above. It fits Crystal.)
Crystal: I died when I was one year old. A demon spirit tried to take over my soul but my soul couldn't handle it....
I woke up in the demon realm. I was scared... I was just a toddler between all those demons. Then I met Viper, Iblis sister. She trained me for all those years. I still remember how Viper sang to me when I was little.  When I first entered back into our world and I saw Christine and how much we looked alike I knew something was up.... Viper said to me that Christine was the reason I became a demon. So I tried to attack her but her necklace protected her and captured me. Making me bound to Christine....
A few years later when we came to this multiverse I was able to enter the demon realm of this multiverse. And that's when I met Cross!Chara. We became friends almost instantly. I was so happy I finally had a real friend and when I realised we both wanted to destroy the multiverse. We became partners (in crime). And when Nightshade was born we planned an attack. But before we could start our plan... He was defeated and dissapeared. I was so angry. So I planned to use your magic Christine to destroy everything once and for all.
Well... we all know how that ended...
Not only did I find out that Christine is my sister I got banished to the deepest depths of the demon realm. But I wasn't going to give up. For years I planned my revenge. I made alleys and we broke free together. We hid in Shadowtale for a couple weeks waiting for the right moment to strike.
And the rest you guys know already...

(And that's all for now guys... sorry I have just to much on my mind right now)
