Castle Redstone

Rajah longs to be a celebrated adventurer, but every quest he can imagine has already been completed by his father, Lord Maharajah. The man has defeated the Ender Dragon, mapped the Overworld, and raised a grand manor house. Rajah makes do with castoffs, including his father's old, grand-sounding name and an old, grand-looking sword. His servant Pal has a kind heart but is no fighter, and his squire Faith is losing her trust in the knight she once admired. Rajah has become a figure of fun, not a hero to anyone.

Everything shifts after yet another disappointing day, when Rajah, Pal, and Faith come across a map. It points to a legendary castle that Lord Maharajah never managed to conquer, a place said to conceal the inventions of a vanished civilization. Reaching that fortress, called Castle Redstone, means crossing dangerous marshes and climbing towering mountains, and along the way the three companions must learn what they are truly capable of.
