What if, instead of going to Ponyville, Twilight Sparkle left Canterlot to go to the Pony Mesa Research Facility?
What if, instead of fighting off Nightmare Moon, she fought off a Resonance Cascade?
And what if, instead of meeting her friends in preparation for the Summer Sun Celebration, she instead met them in the aftermath of the Resonance Cascade?

This is the story of Twilight Sparkle, as she takes on the role of Gordon Freeman from the original Half-Life, and the friends she meets along the way.

Thanks to HiveLordLusa for the picture.

Stuck in a time not her own, with two mysterious ponies she's never met or heard of before, and Discord and Sombra at the full height of their power, will Twilight be able to prevent the mutual destruction of past and present Equestria?

This is a collab between two authors, Default and Nerobot

Also, huge thanks to our editor/pre-reader Stanku!

Run. Think. Shoot. Live. Pony.

On 5/16/02 (Human Calendar) and 5/16/11 (Equestrian Calendar), an immense resonance cascade event connected three different dimensions in a massive disaster that would change the face of their worlds forever.

Doctor Phase Ray is not having a good day.
Things started off simple- system crashes, equipment failures, and daylight savings complications. But when a routine sample analysis goes horribly wrong, Phase Ray is forced into a battle for her very survival, along with many of her colleagues...

Doctor Gordon Freeman is not having a good day.
Things started off simple- system crashes, equipment failures, and ruined breakfast casseroles. But when a routine sample analysis goes horribly wrong, Gordon is forced into a battle for his very survival, along with many of his colleagues...

When Twilight seeks to return to the human world through the magic mirror, something goes horribly wrong. Now trapped in a galaxy far, far away and in a body that she barely understands, she seeks to find her way home. But when she's pulled into an interplanetary war for supremacy her wit, skill, and will to return home will be tested. In the end, it will come down to one decision for Twilight: Light or Dark?

Some said that I'm a Spirit...
Some called me Monster...
Some even Hero...
They were wrong. I'm just a girl that wants to get home to her family, to get her life back and if I have to carve my path with my Black Blade, then so be it!

"This is a tale said around many a camp fire here in the Mojave. Some will tell you its a tall tale made up by drunken caravaners to past the time on the long and winding roads, but this is a true story. So come take a seat by the fire I have a fresh piece of mole rat in the pot if you care to indulge me with an audience... the story is of the strange pair..."

Thank you to frieD195 for editing and making it look pretty!
Will add tags as they come up.

Twilight and Discord are a long way from home, and have to journey through a realm of madness and chaos to get back to Equestria. Fortunately, this is Discord's speciality, so Twilight is in safe hands. Less fortunately, all the local gods want him dead.

Part of the Borderworld.

Rainbow Dash has a freak accident while performing a Sonic Rainboom, and awakens to find herself in a strange new world, with strange new abilities.

After saving Cadence from the Changelings, Twilight was thrown into another world where she is human. She marries a human and has a daughter named Aurora.

Twelve years passed and the portal to Equestria opens again.

However, Twilight is kidnapped by the fabled Glizani Court and Aurora is alone.

Now under the care of the Bearers of the Elements of Harmony, can Aurora adjust to her new life and new body while waiting for her mother's return? And will those who were present at the wedding rehearsal twelve years ago overcome their guilt for Twilight?

This story was inspired by the concept of Survivor's Guilt after playing American McGee's Alice.

Update: I've added the "Gore" tag due to nightmares and possible future battles.

Each member of the Rainbooms is going to be having their own adventure.

With Spiderman away from the city, it's down to Twilight Sparkle to fill in. Things may go well at first, but when Canterlot's most wanted return to the streets, things might get more difficult.

So she must use what Spiderman has taught her to protect the city from villains like Juggernaut, Tinkerer and more.
