Lord High Admiral functioned as both a military designation and grade, a status that Leia Organa, the Princess, suspected that Harrsk, previously an Admiral within the Imperial forces, had unilaterally bestowed upon himself.
Within the narrative of Children of the Jedi, the title "Lord High Admiral" is connected to Harrsk solely through Leia's internal monologue. She refers to him as "the self-styled Lord High Admiral Harrsk," and subsequently as "High Admiral Harrsk". Furthermore, Gial Ackbar calls him "Admiral Harrsk," while C-3PO designates him as "Grand Admiral Harrsk." In addition, The Essential Atlas also mentions Harrsk as a "Lord High Admiral".
