Keslovar was a psychiatric research academy on Vulcan.
In 2401, Admiral Jean-Luc Picard proposed that his son Jack Crusher go to Keslovar, after learning that Jack had inherited genetic modifications that the Borg Collective had made to Locutus. Jack rejected this notion, asserting that Keslovar was "a prison where they can mind meld and lobotomize the Borg from [him]." (PIC: "Vox")
