Onthrilaenthor

Onthrilaenthor is a ruined Eaerlanni settlement in the eastern Star Mounts. It was created for the elves by the Ammarindar dwarves and consists of miles of tunnels and chambers cut into the rock, including vertical shafts to an area near the summit of the southern Star Mount. The presence of stables near this shaft leads to the belief that it was used by the Eaerlanni elves for aerial mounts. Onthrilaenthor is affected by strong winds, sometimes making it difficult to walk through the tunnels.

After its disuse, Onthrilaenthor was inhabited by harpies until they were driven out by the deep dragon Onskarrarrd.
