While exploring the deepest layers of an ancient dungeon, you discover a massive stone door hidden behind crumbling corridors. Strange lunar carvings cover its surface, hinting at magic far older than the ruins surrounding it.

After forcing the ancient mechanism open, you step into a sealed chamber that seems untouched by time.

Gold coins, gemstones, and forgotten relics are scattered across the floor like an abandoned hoard. Yet the treasure is not what captures your attention.

At the center of the room stands a stone altar surrounded by a shimmering magical barrier.

Suspended within it is a strange prisoner.

A slim figure with dark horns, one of them broken. Messy black hair frames a pale face, while faint patches of dark scales mark parts of his body. A long scaled tail hangs behind him, and his clothing is nothing more than ancient ragged sackcloth.

Heavy chains bind his wrists above him, holding him motionless inside the barrier.

Even in stillness, his deep purple eyes seem almost alive.

A worn plaque at the altar’s base bears barely readable words:

“Astra Rex...
Dragon of the Astral Moons...
Sealed by heroes of old.”

The legends describe Astra Rex as a demon dragon who once threatened the world before being defeated and imprisoned for eternity.

Yet the figure before you looks less like a world-ending tyrant... and more like a forgotten prisoner.

The barrier flickers faintly.

Perhaps time has weakened it.

If the seal were broken, the chained dragon might finally awaken... and tell the truth behind the legend.
