The gods of Koth are rarely beings of cosmic power, all-pervasive and all-encompassing. Most often, they are corporeal beings – powerful ones, to be sure, but mortal and finite. The weakest gods are no more than ‘divine animals’, totem beasts associated with small tribes of beings. Rarely do such creatures have more than a meager amount of divine power – they grant minor miracles to their followers, subsist on the offerings made to them, and may defend their people in time of need, but feats such as earthquakes, floods, and other grand displays are usually beyond them.
As tribes grow, intermarry, and conquer each other their gods will often as not do the same, often with the gods uniting in the form of chimeric beasts such as the griffon, the manticore, and many others. It is thought that many of the most common chimeric beasts are in fact the mortal servitors and descendants of the forgotten gods of lost civilizations.
Larger civilizations sponsor more powerful gods (it is a not uncommonly known fact that gods subsist upon the worship of their followers), and as the deity gains power it tends to take upon the appearance of its worshipers. In addition to its previous powers, most deities can change shape in a limited fashion, have some control over the weather in their own domain, can heal or harm with a touch, and other such feats.
The most powerful deities come from the union of civilizations, either through peaceful means or by conquest. As citizens of different races and cultural mores come together, the gods appearance tends to be dependent most upon the concepts it espouses, rather than the beast it once inhabited or the race of its original patrons.
There are of course variations upon this theme; some deities wed their power to a dynasty, forming a civilization ruled by god-kings. Some gods are born out of the spirit of a former mortal after their death; in the rarest cases some mortals steal or earn divine power during their own lifetime. Some deities are the children of other deities, and subsist off the power of their parents until they can find their own worshipers (a common occurrence when a deity wishes to form a pantheon.)
A deity only has power within its own domain – when priests of a given deity travel out of their deity’s lands, they rely upon alliances made between neighboring gods to empower their miracles. In some cases, deities will force their neighbors into such an alliance, then send their servants into the other god’s domain to gain worshipers while depleting the power of their neighbor. The politics of the gods are complex and diverse, inspiring many a mortal saga.
