House of Krell
From Star Trek: Theurgy Wiki
This House was one of the families that was struck by the Earther Augment Virus and became QuchHa’. While this House never rose in status, it distinguished itself by continuing to serve the Empire during the post-Organians covert conflicts with the Federation, including the House head himself leading a successful mission to Neural. The House has continued to have members who serve the Empire, but never enough to rise in status, even after the Augment Virus was cured.
