Notes
Celestian has few priests, though many venerate him
The starlight prayer requirement may be waived en extremis, such as when a mission for the deity takes the priest underground for extended periods (i.e. the GDQ series), hence the lower cost. This should not be done under normal circumstances.
The casting of spells by priests of Celestian involves a noticeable chill in the air, from the intrusion of Astral energies.
Background
Celestian is a brother-deity of Fharlanghn, although his sphere deals with the void and the stars rather than with the Earth. His priests are few, but they are actively involved in the affairs of Oerth.
