Meet Flintsteal Lockwood: a talented, young Earth Pony from the island Swallow Spells. All his life, he wanted to do something: become the greatest inventor ever! So, he plans to build the best invention Equestria has ever seen. A device that would cause more harm than good. A device... that turns water into food. When the Mane Six travel to the island with the Saviour, things aren't as nice as they'd hoped. Everything was grey. But meeting Flintsteel? The adventure had just begun.
