Observatory (Machaon Quest 1-3)

Synopsis
Once we got closer to the stone giants, we saw an ancient observatory in the center of the circle. The observatory's tower was half destroyed. Yet we immediately noticed many ingenious devices, such as weather vanes, astronomical instruments, and even a huge sundial.

Completion
The observatory was both a fortress and an observation post: from its tower one could see the entire Machaon to the very foot of the mountains. On the ground floor, we found some spears that were once used to defend the Emerald Valley.
