Aside from the ruins of the old city, the ruins of Sidos are the closest ruins to Brightshore found so far. They lie 1 day's travel to the north. These ruins were found and explored soon after the founding of Brightshore.

In the winter of Year 23, a party of adventurers revisited Sidos and found a reconstructed teleporation circle there of ancient origins. It took them to a temple of unknown location where they encountered some sort of construct guarding a strange crystalline artifact.

This turned out to be a trap set by Magu. When they returned, she tried to kill the party and take the artifact, but she failed and was forced to retreat. During the battle, the teleportation circle was destroyed.
