A company from the far Eastern region of Equestria has created a new device for entertainment. After becoming well known in that region they seek to bring it westward, so Princess Celestia sends a few models across the local region of Equestria as a means of testing it's appeal.
The Mane 6 are recruited to be one of the 2 testing groups in Ponyville, so they sit down through a steady stream of games to see if it should go throughout all of Equestria.
They play, they laugh, they may even become frustrated but, to be sure, these games will not be something our heroines will not forget soon.

A mysterious stallion wielding incredible powers, with the help of mystical devices from Starswirl The Bearded's era, plunges Equestria into the pre-classical age—a place in time where questing and adventuring is first and foremost. The magical effects at play give the Cutie Mark Crusaders a new world, new abilities and a new challenge to overcome, all while fending for their lives in an ancient conflict.

Featured Story

When Twilight had settled into her home/workplace at the Golden Oaks Library, she noticed something absolutely dreadful—almost no one came in for a book. As a matter of fact, ponies only seemed to enter the tree when there was an event or some mandatory meeting.

The only ponies she could remember actually borrowing a book were her five close friends and Cheerilee. Not to say that Cheerilee wasn't a friend, but she was legally required to do so as a teacher and thus didn't count.

But after Pinkie inadvertently plants a certain seed in her head, Twilight thinks she knows exactly what will get these ponies' attention.

A party.

Big thanks to those who took their time to help me polish this thing.

Twilight Sparkle has been stuck on Earth, as a human, for a while now. It wasn’t planned, but the human girl that she stays with is at least very helpful.

A side story of Merlos the Mad's A Twilight Landing. It takes place just after chapter twenty-four. If you read this story by itself, most of the jokes will still make sense. This may also be considered canon.

I have been informed, that the cover Merlos found for this, is art by MegaSweet!
