The Lanthanide Mine was a mine located in the Juran Mountains on Alderaan that at one point was used for lanthanide production. It was eventually abandoned and by c. 3643 BBY was inhabited by the Killiks of Ukunuku nets, led by a Night Herald. Several members of House Thul were held captive in the mines, and at least one them - Daria Thul - became a Joiner.
