The mere presence of deities and the divine makes you sick to your stomach, and their worship is something which insults you greatly.
You're treated as having an Alignment of 1 with all deities and religious organizations, and cannot change this.
Divine spells or spells cast by characters with the Divine Inspiration trait take a -10 penalty to hit you, and only affect you half as well (bonuses/penalties are halved to a minimum of 1, healing/damage is halved to a minimum of 0, and so on).
