Harper suffers from Artemon syndrome, a psychological condition where an individual feels intense homesickness for a celestial body for which they are not native to, and oftentimes never resided. The condition seems to have emerged only in the past millennia, reported affected individuals on all Consolidated Nations. Typical symptoms of homesickness are displayed: frequent crying, anxiety and social withdraw. A distinct aggression towards others is typically present. Condition named after Vanesa J. Artemon of Hovuna, S5, after poisoning co-workers with the heavy metal thallium.
