The Prince and Princess: The Secret of the Golden Key

Two Kingdoms and One Adventure

Once upon a time, between two green hills, there stood two kingdoms:
one was the Sunny Kingdom, where Prince Arthur lived,
and the other was the Moonlight Kingdom, home to Princess Lily.

They often sent letters to each other, carried by a talking dove named Pip.
Arthur loved inventing things—from steam-powered boats to self-pouring teapots—
while Lily adored solving riddles and making up stories for her people.

One day, Pip flew in, all flustered.
“Trouble! The River of Light between your kingdoms has disappeared!”
“What do you mean, disappeared?” gasped the prince.
“Vanished! Without it, everything around is growing dark!”
