Nature is a harsh mistress, granting power to some as a part of their respect for its place in the world. The path of a druid is one of even meditation and guidance. A grand druid denies the uniformity of nature, seeking power through a closer connection and bond with a smaller part of nature at the expense of the whole. Their deep connections lead them to become leaders for other druids, and they gather in councils of mutual respect, if also of opposition. Grand druids lose touch of the world of animals and plants early on in their spiritual journey, seeking something purer and deeper. As they reach into themselves, they find a part of themselves which is of a distilled part of nature. This element then begins to purify them as a part of itself, changing them and their powers. Grand druids are part of the higher echelons of druidic society. Respected in the appropriate fey court, able to attend druidic councils and often controlling their own grove, they are found most often tending to their followers. While still searching for a grove to rule, they make formidable opponents with their unrivalled power over an element, and an incredibly powerful elemental form to destroy opponents.

For ease of use, the four elements will have their effects specified - a grand druid of ooze could exist, but would have to have powers worked out on a case-by-case basis. In addition, quasielemental grand druids are vanishingly rare.
