The world has two moons: one large (the perfect) and one small (the imperfect). The Zalitraeq year is 8 months with 4 seasons of 2 months each. A Zalitraeq cycle is a period of 16 months. For the first year of the cycle, each month starts with the perfect moon full and ends with the imperfect full; in the second year, each month starts with the imperfect moon full and ends with the perfect moon full. This forms the basis of the signs. The world's sun is a white dwarf; residents of Zalitraeq kingdom believe in the heliocentric theory.
