One day Twilight and Rarity were walking around Pony Ville when Rarity noticed something gleaming on the ground. Rarity looked at it like a fish looking at a worm, or fruit bats at an apple. She then wanted it examined but it was lodged in the ground tight and deep. Twilight summoned spike to bring a shovel and dig it up. As soon as spike stuck the shovel in the ground at that location, the ground started shaking.
Twilight asked spike to write to princess celestia about whether she felt the quake. To her surprise Princess Celestia had felt it along with Princess Cadence and princess Luna. The next morning there was multiple lights in the sky that no one had ever seen. Even Zecora had never seen anything like it. after the lights faded a wormhole appeared sending some ponies through it and bring some new creatures to equestria.
