This is the first book of The Humanity Within Trilogy. Its sequel is What I've Done.

I wasn't always like this, a monster, running through the woods on an alien planet. I was once a man. I had dreams, a girlfriend, and a great job.
Then They came. In the middle of the night, They scooped me from my home, and... changed me.

Now I'm a beast, a demon the like of which the world I've become stranded on has never seen before, scraping by on the fringes of society, hiding from the natives, and doing my best to avoid notice.

After all, who could ever be friends with a monster?

An English knight married a kindly woman, touched in the head, who thought she was an alicorn. She was right.

Then one day Cecilia disappeared.

He knew that Cecilia vanished into the side of the statue, the same place she lamented the 'mirror closing' two and a half years ago. He threw a rock at it... and it vanished. It was true. He had to find her.

He didn't care about Cecilia's madness, about this 'Equestria' or her obsession with ponies. He loved her. He loved her enough to walk into Hell itself. He would bring her back, no matter what.

Red Team had been given an assignment. It wasn't the usual sort of assignment. They were assigned to defend their base 'until further notice'...and then never received notice. All announcements sounded pre-recorded, and enemy assaults were few and far between. The enforced inactivity was slowly fraying the bonds of the team...

...until something unexpected arrived. A tiny creature appears one day in their fortress, in need of compassion and care. Somehow, she finds that in this group of strange individuals, as she becomes their baby.

There comes a time when the light must go out; but how do you know if you've burned brightly enough?

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.

*6-16-2017 Edit, added Rainbow Dash tag because it triggered knighty.*

When the light dims and the flame burns out, the magic inside us all will forever endure.
