The Church of Light is a culmination of all 12 of the good gods (10 Gods of light, Bahamut and Hephaestus) and in a minor way the three dead gods. It is a place of convenience for the people to give alms and other offerings to whatever god they need at the time. You will find a church in most towns and cities. They can be run by a cleric or a priest (Cleric with no spells).
