The Second Doctor is facing exile, having beaten the War Lord, he is now under trial by the Time Lords. Having faced the threat of exile, he is given a choice, some may call him foolish for taking it, but nonetheless the Doctor takes this choice and is thrown into an adventure not even he could predict.
Set in Season 1

In the Toyroom, a game you’ll play.
If you win, you’ll be okay.
But do be careful, that you don’t stray.
If you want out, it’s the only way.
But you’d better, hope and pray,
That you don’t, fade to gray,
Or in the Toyroom, you will stay,
For the rest, of all your days!
Good luck, everypony!

Cut off from the TARDIS and without the Doctor's help, Derpy and Star Hunter must win at Discord's unfair games to survive and escape this realm outside of normal reality. But why has Discord brought them here? What is he really after from the Doctor? And can this tagalong Pinkie be trusted?

(Doctor Who crossover; adapted from the Classic Who story "The Celestial Toymaker". Three of its four episodes are "lost" and exist only as recorded audio and screenshots, so I thought I'd do my part in "saving" them. My version aligns to the original in outline only.)

The Doctor and Derpy are in 1832 Equestria, where they hear a fillys story about a mysterious stallion who is always seen sitting in a bench in the woods, but when you get close to him, the stallion disappears. Is it some kind of optical illusion in the leaves, or is something more going on here? Could this filly's story actually be true?

For centuries and millennia, the Doctor battles his own set of enemies while exploring the universe.

The Master once again is up to no good. The story is usual, right? The hero saves the day and evil is defeated no more no less.

However, the Master is bored. Recently, the Doctor has lived in Equestria, serving as an ally for the Mane Six and their friends. Now it is their reluctant battleground both physically and spiritually.

WARNING: IT'S NOT THAT KIND OF STORY.
Sure, it deals with younger versions of The Doctor and company, but it won't be nothing like that! There won't be no baby talks, no diaper changes, and of course NO BREASTFEEDING. It will focus on growing up, both physically and mentally.

This story is a sequel to Meta Gamer in Equestria: Champion's Folly

For returning MGiE readers: This story is at the end of Moss's arcs. He's had his adventures. His magic has evolved and grown. The story will not be an exact spiritual successor to the others involving Moss. The story will go in a somewhat different direction and will likely have an effect similar to the Star Wars prequel trilogy had compared to the original. It was Star Wars, but "not the same" Star Wars.
For new readers: This is the 4th in a series that originally had 3 main installments planned with lots of details I won't be covering. It's a DnD 5e crossover with a four way multiclass and all the convoluted mechanics involved that can't be fully summarized to get you going. Read without reading the others if you want, but do so at your own risk.

He was forced into a war to protect Equestria and the world of Equis on the whole. The land was protected. Years went by. Promises were made, and promises were kept.
A spirit-turned-owl he first hated grew to be his best friend over the years as he spent his time stuck on Equis. The owl was always straightforward with him when he asked something. Only one minor item did the owl make a point to beg him not to force the owl to tell when it came up. It was not a big deal to him, as he understood it was for a promise to a lost love. Some secret the owl wished to take to his grave, he was certain. What he didn't expect was how much it would end up involving him and how much more it would end up explaining.
