Sol-Oltharë; meaning "Tower of the Moon" in elvish, is a powerful military outpost, located in Drakhara, north of the Grafenmyr.

This dark and fearsome castle was built by the Dark-Elves in the Second Age. After the elven nation of Drotharë collapsed, the fortress was taken over by the kingdom of Adar. Today, it used by Sorimmar’s armies.

The fortress guards the junction of the Pentamundë Road and the Jade Road.
