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.

Now with a Russian reading by SviMik

Against your better judgement, you ended up having three little girls that you have to take care of all by yourself now.

As much trouble as they can be sometimes, you still wouldn't trade them for the world.

Set in the Equestria Girls universe!

When Twilight Sparkle (the scientist one, not the otherdimensional pony princess) predicts an oncoming magical calamity, it's up to Sunset Shimmer and her friends to stop it!

Now, they've got just two days to cover hundreds and hundreds of miles to get to exactly where the dimensional incursion is going to take place.

Good thing it's Spring Break. Road Trip!

During an experiment with new magic. Princess Twilight Sparkle suddenly finds herself in a strange new world and in even stranger company.

Kai is your everyday guy. He wakes up, goes to work and then comes home again, a monotonous routine that is his everyday life. That is until a talking, purple horse appears in his apartment. Well… so much for monotonous routines.

The Princess has a secret or two though, perhaps a new friendship will help her forget some old ones?

Diamond Tiara's joy at her newfound outlook and friends is shortlived. Exiled to her bedroom while her uncompromising mother decides what to do with her, she can only listen in as Spoiled Rich tells her too-meek-by-half husband Filthy EXACTLY how useless his daughter is. Then, there's a sudden knock on the door... and Tiara's adventure is about to begin.
Set after the events of 'Crusaders Of The Lost Mark'.
