Lost in Reefs

In Lost in the Reefs, you are the only person who knows about the ancient civilization of people and dragons, a mighty alliance of wisdom and power. A year ago you found some old scrolls with scarcely discernible handwriting and were astounded by what you managed to read. The dragons really existed - golden, silver, emerald green dragons; huge creatures flying across the mountain ranges, breathing fire on enemy troops, carrying enormous cargo, patrolling the borders, soaring high above the clouds. The people were invincible together with the dragons, but they could not resist the nature. An earthquake destroyed the wonderful dragon city... And all that survived the earthquake sank to the bottom of the ocean.
It was impossible to forget about the secret knowledge that was probably kept under the ancient ruins, so it was time for you to organize an expedition. Now you have found the right place! Start digging out and explore the buildings. You must work hard - the Heart of the City is so close, but difficult to discover...
