Knowledge (Arcana or Planes): Astrological considerations are often observed when attempting arcane rituals and divine rights. Of the seven astrological bodies seen from Faerun (the Sun, the moon and five planets), each holds some measure of arcane importance, religious or pagan custom or cultural significance. It is believed that the Netherese were the first to give names to these bodies, and those names have since spread to the rest of Faerun. Sometime in the prehistory of Faerun, the planets, apparently due to their colors, became associated with the elements and, later, with the Elemental Gods. While this still holds true today in some cultures; other peoples have associated the planets with their own gods, rituals and tales.
