These are all of the deities that exist in my game world. The writeups from the Deities and Demigods book have been included as guidance. While the general information about alignment, appearance and traits can be considered fairly accurate, note that the actual beings are probably more like a hundred times as powerful as listed - a greater god probably has more like 50,000 or more hit points, would have an armor class at least -100, would attack many times each segment, hit for a hundred or more points of damage each time, and so on.
You can also treat notes in deity writeups that say things like 'only elves may be priests of this deity' or the like as lore, not fact.
Under each alignment is the outer plane that beings of that alignment most often inhabit, although this is not always exact.
Philosophers and priests have many debates about deities, where they come from and what exactly they are. Since there is undeniable proof that priests have powers that seem to depend on their faith in widely different deities, who have different origins and are not related, one of the most popular theories is that while the claims that most pantheons have to be the most powerful, only true gods, and creators of the universe are almost certainly false, it is apparent that these beings do possess power far beyond that of mortal man. This power may derive from the worshipers they have, which at first seems like a circular proposition - how did they become gods, if they originally had no worshipers? Most likely the answer to this is that these beings were originally very powerful mortals, who became admired and respected by large numbers of people before they died, and this gradually grew into a form of worship after these beings moved out to outer planes after their deaths. In a feedback process, these beings became more powerful, exerted more influence on the mortal world, and this gained them more followers, who eventually founded cults and religions, channeling more power to them. This means that it is likely that somewhere in the world, one could find the original place where each mythos began. An example of one of these might be the country Fennoscandia, where nearly godlike beings of the Finnish mythos are known to exist.
The one apparent exception to this theory is the being known as Eru, long ago believed to be the creator of the world and all early life. His origins are not widely theorized about; he was all but forgotten and considered to be a legend (except among the elves) until he reappeared in the early 1140s and started a war that saw to the deaths of many of the beings who claimed to be deities, and the extinction of entire mythoi - including the Chinese, Japanese, Indian, and several others. Those listed below are the only survivors of that time. Eru may be a deity from another reality, who escaped to form his own world, or he may indeed be the progenitor of all. It is doubtful if this question will ever be resolved.
Next to each deity's name is the mythos to which they belong. Also, while some of these are listed as 'lesser gods' in their descriptions, in the years following the Judgement War, all have risen to the status and power of greater gods.
Also note, certain beings not usually thought of as deities are included on this list, such as Demon Princes. These beings have no mortal clerics, but are recorded as part of the power structure of the most powerful beings.
