THE STORY BEGINS

You’ve just stepped into something extraordinary.

Mira has found the old hilltop observatory and wants to reopen its welcoming light for the village below. The preparation journal has come apart, and its paper sky charts conceal the control instructions. Rejoin the notes, turn an invented star card and trace ten connected discoveries. Every rule is supplied; no real astronomy knowledge or equipment is required.

Work through 10 connected puzzles: joining strips, indexed arithmetic, pattern rotation, reading windows, diagonal navigation, symbol equations, elapsed time, filtered initials, digit transformation, linked final code, and bring the clues together for a final answer. Play at your own pace, with two progressive hints for every puzzle.

Play times are estimates and vary by group. Ages are guidance; younger players may need an adult.
