Princess Twilight Sparkle and her friends are moving all of the books from the Castle of the Two Sisters Library into a brand new soon to be open Grand Library in Canterlot. While sorting through the endless knowledge of the past, Twilight comes across an odd looking book with the title ‘Overworld’, curiosity gets the better of her as she and her friends are transported to a strange block world. They must now find a way back to Equestria before something happens, and with a little help from a brave Miner named Steve, they may just do that. But not everything in this world comes in peace, as they are being watched from a far by a pair of bright white eyes that glow in the darkness.
