Phyrrys was the apprentice of the legendary astronomer Scorpius in the Fourth Age. Following Scorpius's death, Phyrrys began work on the calendar of RuneScape. Phyrrys was unable to make his calendar account for 40 days of the year. Many years after his death, an astronomer discovered the remains of his journal, and solved this problem by adding the 40 days in between Septober and Novtumber. This month was named the Ire of Phyrrys in honour of his work.
