Chapter 2: Training and Memories

The cool air outside my cabin calmed my nerves as I made my way up the mountain. After changing, cleaning up the few dishes, and feeding Cozzy, it had gotten late. The moon was beginning to rise up in the dark sky, and a few stars were starting to twinkle above.

I had gotten several texts from Alphys and Undyne questioning if I was still coming, and I felt a bit guilty for taking so long. As I run I enjoy the feeling of being in my normal form. I felt so relaxed as my small paws hit the dirt path and the sound of crickets ring in the air.

As I come close to the top of the mountain my ears pick up the sound of quiet talking. Two voices, Alphys and Undyne. I slow to a steady trot and sneak off the path. I silently slide through the brush and peak up at the small clearing the pair are in. They seem to be alone, no surprises.

I must have made some noise as I shuffle around to reveal myself because alphys' gaze snaps up and she looks around wearily. She slides in front of Undyne and growls, silencing Undynes y'all of some show.

I quickly reveal myself, earning a nervous look. "Is that.. a fox?" Alphys asks undyne suspiciously, who nods. "What do we do?"

"Relax guys, it's just me." Both jump at the sound of my voice and glare at me.

"G-geez you scared th-the l-life out of m-me!" Undyne shouts and Alphys is ok shakes her head. With a comical dark blue poof of smoke I return to my half human half Fox form and walk up to the pair.

"So why are we here?"

"Training!" Alphys exclaims, and leads me into a small cave which eventually opens up into a huge castle.

"At night? And trading for what?"

"I just want to see how strong you are!" She responds with a huff. I look at undyne for answers and she just shrugs and smiles at me.

"Okay.." I respond simply as we pass a throne. When we exit through next door we enter a long corridor lined with pillars. For some reason, this hallway gives me the creeps. Maybe it was the light eerie glow of the moonlight streaming in through huge stained glass windows. Or maybe it was something else. Something I hadn't been told yet.

The walk through the underground was relatively tame. They asked a few questions about me, and I asked a few about them. After 15 minutes of walking we stop in a huge open area in hotlands. I was not much a fan of hotlands, I much preferred cold weather. Which I said in complaint only earning a sympathetic look from undyne and an eye roll from Alphys.

"So how does this work?" I ask after a moment.

"WE FIGHT!" Alphys roars, then rushes at me. At the very last second before her body could hit mine I shrink into a mouse.

She turns around and shakes her head, "cheap move." I turn back to my normal human form and chuckle.

"Alright, come at me!" I challenge and glare at her. As before she runs at me, this time I sidestep and put out my leg, sending her tumbling to the floor.

"Seriously?" Alphys growls as she scurries to her feet. Undyne giggles behind me, earning a halfhearted glare from her girlfriend.

She looks about ready to shoot me with a magical attack, but before she can summon anything I distract her by changing into a bird and flying towards her. She gasps and ducks out of my path, which makes me swerve and come at her from behind. She chuckles then whips her tail up to hit me, sending me flying up towards the ceiling.
