When Brightshore was first founded, it was built on top of the ruins of a much larger city, whose name is now known to have been Cathorn. The ruins of this city to the west of the Olteus River are still largely unexplored and unclaimed. Dangerous creatures of all descriptions have been discovered within.
Multiple parties of adventurers are currently working to tame the ruins, piece by piece.
Below are some of the locations that have been found so far.
A large abandoned structure. Nearby, adventurers Atwood and Zerck are starting a ranch for horses.
A ruined armory in the ruins was found by adventurers. Texts related to the summoning of devils were discovered inside.
This ancient tower once housed a massive bell. It was recovered by a party of adventurers.
An ancient shop in which lizardfolk and a banshee were discovered.
In area M10 of the ruins, adventurers discovered a building containing a large hole leading down to a temple-like structure. They encountered gnolls and a devil within.
A door in the ruins leads to a basement where some adventurers encountered some creepy haunted dolls.
A magical chocolate factory found inside of a restored building in the ruins.
An amulet was found in this tomb and taken to Brightshore, which led to the awakening of a massive golem that destroyed most of the River District.
The cult of the kraken once had its headquarters in the ruins by the shore of the bay. In the adventure in which the cult attempted to steal Gombold's ship, the Tide Dancer, the cult was apparently exterminated.
Somewhere in the ruins is a building found by adventurers that contained a lightning rod and was summoning continuous bolts of lightning.
A tower where a manticore and its baby were found.
A stairway in the southeastern outskirts of the ruins leads down into the chamber where Council leader Orrin's son Marco was seen summoning devils.

A hole in the ground by the bay leads to a basement where several duergar and a mindwitness were found.
Section N12 contains a large two-story building. Adventurers found several elementals and myrmidons within, going about various tasks, as if programmed.
