18 years ago, a strange, celestial body crashed just on the outskirts of Canterlot. A mysterious box was found and studied in the Canterlot Research Facility. Despite the time and effort, its secrets have yet to be unearthed....until now.

6 months had passed since the disappearance of Micro Chips' brother, Gizmo. But upon a mysterious delivery, he and his friends Flash and Sandalwood work to crack the mystery surrounding the incident.

Now, rampaging monsters run amok in Canterlot City, emitting a strange gas that turns others into the same creatures. What's worse, Equestrian Magic seems to have no effect. Fortunately, Gizmo had left something behind. A particular system needed to combat these creatures and uncover the truth.

Flash Sentry now takes up the mantle, to build the winning formula.

Edit 6/24/2020: This story had been featured. I am surprised and grateful. I didn't expect it to happen.

Flash Sentry is Captain of the Ponyville Guard, personal bodyguard to Princess Twilight Sparkle, and a big brother to Scootaloo and First Base. One of these roles is harder than the others, and not even Flash's military training can help him with that.

Six years ago, Flash Sentry met Wallflower Blush, the awkward new girl moving to a room almost opposite his own, for the first time.

Today, Flash Sentry is meeting Wallflower Blush, a mournful, broken soul reeling from the aftereffects of a year of causing so much hurt to others, for the first time.

He doesn't remember her. Wallflower remembers him.

Yet she wonders if he understands her better than she does herself.

Cover art edited by myself using a still from the first Equestria Girls movie.

Depending on the time period, some sections are written in first-person present-tense, others in second-person past tense. In all cases, the POV is that of Wallflower. Not in continuity with any of my other stories.
