According to the Chaldean philosophy, supernatural entities constantly try to affect the daily lives of men, and that by performing suitable rites the actions of these entities may be influenced. The Chaldeans believe the supernatural entities to be invariably malevolent, or at least indifferent, so sacrifices are needed to appease them. If an interesting enough sacrifice is provided, one may even presume to ask for favors.

When the Babylonians conquered the city-states of Sumer, the rites of the priest-kings of Kish and Erech were replaced by a more organized religion. The Sumerian tradition has endured for thousands of years, eventually becoming corrupted from rites for the good of the community to a path for personal power.

Most Chaldeans are now devil-worshiping witches and warlocks, but also cults worshiping malevolent spirits or demons for fear of punishment or hope of reward can be counted into the philosophy.

Chaldean Magical Tradition

The Chaldean tradition is based on ancient Sumerian magic where one requests or demands service from a supernatural being. One can use such magic only by serving a suitable entity, the easiest masters are demons who are always looking for souls of power-hungry men. Sometimes Elemental Princes can also grant favors like this.

Many witches start by serving a weak demon, but later try to enslave their former master to gain a semblance of freedom of choice on their actions. It's no surprise that demons resent being enslaved, so witches choosing this path must pay for their freedom by living under fear of rebellion and retribution. By enslaving weak spirits an less ambitious warlock can gain minor magical powers without great personal risk. Powerful masters often present their lesser kin as slaves to their more powerful servants to fulfill everyday magical requests.
