"A man finds a Queen Elizabeth letter about a secret magic organization. Later, a boy’s parents vanish after a raided house, leaving a color‑changing cloth. With his fat friend, he finds a mind‑activated box showing a lion crest. They go to the building with the crest, fall through an elevator‑slide into tunnels, ride a dragon subway, reach a castle, see magic arenas and magic guns, and learn his parents are wanted in the magical world."
