Whiteleaf is a world that was built to last; its gods are the last survivors of a previous creation which was unhealthy enough to be capable of destruction, and unstable enough to actually fulfill that potential. When they created their new home, the deities knew that they had to preserve the vitality of this world by allowing diversity to thrive within it, even though such radical differences among the world's forces would inevitably provoke the kind of conflict which could endanger the realm's survival. Put simply, a world of perfect safety is a world of stagnation and ennui, whose inhabitants will likely commit suicide out of sheer apathy, or simply waste away into feeble shadows of themselves. Thusly, to keep the world vibrantly alive, the gods had to give it the possibility of tearing itself apart; such paradoxes are common in the realm of the divine.
The number 4 is magically significant on Whiteleaf (in somewhat the way 7 is a recurrent motif throughout the Judeo-Christian tradition from which our modern civilization arose, expressing itself in everything from the days of the week to the number of colors claimed to comprise the rainbow). The maximum number of gods which can ever exist in the Whiteleaf cosmology is 4 raised to its perfect pyramidal extrapolation - (4 ^ 1) + (4 ^ 2) + (4 ^ 3) + (4 ^ 4), which is 4 + 16 + 64 + 256, or 330 in total. Some theologians have speculated that the true forms of the gods (who are known to operate mostly through avatars projected remotely, so that even in their celestial homes they may well not be truly present) are all gathered in some vast incomprehensible hall, where each one sits upon a throne wherefrom their power is truly granted; if so, then there are 330 such thrones in that hall. (The knowledge that a rare few mortal beings have achieved apotheosis seems to support this theory; some who have sought this goal simply failed, when there was no apparent reason why they should, and one possible explanation is that there simply wasn't a "seat" open on the "divinity council" at the time.) Of this potential number of gods, the actual number tends to fluctuate, as minor godlings slay each other or waste away from neglect, and new ones arise from either mortal origins or through the activities of new faiths. At any given time, there are probably about 300 actual gods, but the four supreme deities are largely uninvolved in world affairs, and the 200-some minor divinities tend to operate on small regional scales. So from a global perspective, most actual "god work" is done by the 80 entities which occupy the two middle layers of this pantheonic pyramid.
For each of the four ultimate gods, their four immediate underlings are each a reflection of some overarching aspect of themselves; each of these is further subdivided to produce its own subordinates, and those too have the potential to branch off into up to four final variations. (This is imprecise language and describes the matter only in terms of an organizational chart; a god which is "below" another god is not necessarily a particularly close relative, nor does it act as the other god's agent, or necessarily even like or agree with it. In some cases, it may be scheming to take the greater god's place by increasing its own power; in other scenarios, the two may ignore each other completely, and be only loosely tied together by symbolism.) The connection may be crucial or tenuous or anything in between, but ultimately the parallels are there for a reason, however arcane and insensible to human perception that reason may be. After all, constructing a universe to be sturdier than other universes generally are is no mean feat of engineering; certainly there are obscure sciences at work, which no layperson can fathom.
