Under the glow of a full moon, the peaceful village of Willowmere gathers for a birthday celebration.

Lanterns hang between crooked rooftops. Music drifts through cobbled streets. Fresh cakes cool on open windowsills while villagers pile gifts high in the center of the square.

But one gift should never have been opened.

It bears no name. No ribbon. No explanation.

When the lid is lifted, silver mist pours into the night air.

The laughter fades. The music stops.

One by one, the villagers collapse into magical sleep.

Everyone… except you.

A forgotten prophecy has awakened. A goddess of Fate is watching. And before sunrise, the birthday celebrant must become more than the guest of honor.

They must become The Birthday Hero.

The Curse of the Long Sleep

The mysterious silver box is tied to Hermatine, the goddess of Fate.

Now Willowmere lies trapped beneath a magical slumber.

Only the heroes remain awake and the curse will claim them too if they fail before dawn.

To break the enchantment, the party must:

• Journey through moonlit forests guarded by Gnolls

• Cross a crumbling bridge over a raging river

• Face divine trials inside the Temple of Fate

• Solve a mysterious emotion-based statue puzzle

• Resist the lure of cursed treasure

• Defeat a Lesser Chimera and its Grotesque guardians

• Return the Jewel of Fate before sunrise

If they fail…

Willowmere will sleep for one hundred years.
