"How did I get here? I was heading to Canterlot to see if I could find any moon stones at the university for my ritual when OH MY GODDESS PRINCESS LUNA!" *I freak out before getting hearts in my eyes and Luna stops looking through the telescope embarrassed*
"Oh um...hello Shade Trotter...I didn't expect to see you here he, he...."
"Oh no the same for me~!" *shakes self out of fanboy mode and clears throat* "I mean: I was going to Canterlot to see if I could buy at least a small shard of a moon stone for my...spell." *Luna raised an eye-ridge at the explanation and she walked up to me and I backed away nervously*
"Shade I know practically all spells involving my moon's elements...most of them are NOT beneficial...what're you going to do with it?" *I start sweating a little and reinforce my mind*
"I'm going to use it to amplify my shadow magic! Yeah! You know how I graduated from the academy with my highest points in controversial magics? Well I found out I can use moon stone to help amplify darkness-based spells and I kinda need it to perform a sealing ritual on a haunted grounds in Ponyville which is more or less why I moved there...he, he...." *She leered at me but I held my weak resolve and she backed down*
"Yes I know such a spell so that's true then. Would you like my help? I'd give you some moon stone if you'd let me help." *I gulped as I looked at her excited face and I felt horrible for lying but had to keep up the facade*
"N-no I need to do this myself. If I don't then I won't be able to improve." *she looked sad and sighed as suddenly the old man who owned the observatory shouted that a few rocks were falling from the moon* "Oh hey lucky me! Thanks for the offer Princess Luna but I've got it under control and now I've got the moon stone to do it. It's been a pleasure your Majesty!" *I hastily rushed out but not without receiving both a look of suspicion and worry from Luna* 'Gotta hurry...I'm not good with lying and Luna's no Pinkie so if I don't hurry she'll figure it out....'
