I stopped a few feet from Pinkie Pie's door, feeling the bass vibrate the ground beneath my hooves. There was an uneasiness in my stomach that I couldn't seem to shake. I paused a few seconds more, preened my mane once more before opening the door and held my breath as I stepped inside. The room was dark, lights were flashing and towards the middle of the floor, there was a mass of ponies dancing. To the left side of the room I spotted a few ponies from my group of friends, but one pony seemed to be missing! I felt the pressure in my chest reside at the thought of this. Good, she's not here. Nothing to worry about then. I stretched my wings, feeling my body relax more as I trotted to the group of ponies chatting in the corner.
