The divines are immortal, eternal and unchanging. The thunderbird is not some mutated bird wielding the powers of the storm, but an incarnation of the storm's nature - unyielding, relentless and chaotic with no regard for the devastation caused by wind and lightning. Not a bird that can be reasoned with or convinced to change its ways, but a force of nature itself, always and forever the same as long as there are storms in the world. An incarnation of the divine is nothing but a thin disguise. It is the clothes worn by a force beyond comprehension that makes itself conceivable to mortal minds. It is merely a wayward drop of water escaping an ocean. Divinity cares for mortals only if it is within its own nature to do so and only on its own terms. Faith is tested when the only answer is silence.
