PHB

Period at the end of work-cycle before the beginning of a new sleep-cycle as Proxi crosses from above to below the horizon, approximately the equivalent of 6:00 p.m. in Earth time. She ached to enjoy a rejuvenating sleep in the safety of her ralkid before six PHB when Proxi tipped below the horizon, and she trusted that food and security awaited her. (7)
