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?

After years of shame and ridicule, archaeologist and explorer Lyra Heartstrings stumbles across a discovery that validates all her theories and ideas in one fell swoop. Along with her best friend, Bon Bon, and her old classmate Cadance, they find themselves faced with a mystery and marvel that may change everything.

Following the next greatest lead found in the database of an ancient race, another international team is formed. Led by Doctors Carter and Jackson, they strike out to explore another network of Stargates discovered in a galaxy on the edge of the local cluster. In the process, their findings will cause them to question much of what they thought they knew.

The adventures continue and unlikely allies will face dangers new and old as the Legacy of the Ancients continue to unravel in the latest chapter of the universe.

This story is a sequel to What I've Done

This is the third book in The Humanity Within Trilogy. If you haven't read the other two books first, go back and do that now. Don't worry, this will still be here when you get back...

Also, if you've already finished this trilogy, you should be happy to know that the next book in the series, A Darkened Sky, is out right now! Go read it, follow it, and all that stuff!

I don't know what to believe anymore. I was sure they were all monsters, all demons bent on destroying any peace I and my new friends might find in this life.

I was wrong.

Instead of burning this world down around me, their weapons are pointed away from the planet, not towards it.

As if that conundrum wasn't perplexing enough, I also have to deal with finding my own place in this odd, yet familiar society. But how does one simply go back to being normal? Especially knowing that the real monsters that caused this mess in the first place could be just around the corner?

After all, it's not like I'll ever see my home planet again. They may not be here to hurt me or my friends, but I still don't trust these 'friendly' aliens to get me a ride home...

A slightly more realistic take on the "Human in Equestria" story concept.

... For a given value of "realistic."

Okay, it's barely realistic but it is a hell of a lot of fun...

Now with an image graciously provided by Page Turner, and an audiobook version narrated by multifanficaday and if you prefer it in German, FrankyDoodle has got you covered!

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

The Princesses find an alien creature barely clinging to life at the scene of a terrifying crash. Can the Combined Power of the Elements of Harmony save it, or more importantly, should they save it? Will the arrival of this strange creature tear Equestria apart?

When President Nixon orders, you obey. And now that he wants Luna on the LM and heading home, how is Neil ever going to convince her to follow?
But it doesn't even get that far, as an innocent mistake endangers the mission.
And even as the mission is endangered, tensions are rising back on Earth. While the drama plays out in Mission Control, just what is going on behind the Iron Curtain?
No one knows, but it's certainly not conducive to Apollo 11's welfare.

Sequel here.
