True elementals

Worshipped as demi-gods in ages past, the true elementals are rather haughty and apt to turn violent if a summoner treats them with disrespect, and most druids worship them or the old gods. They answer the Elemental Magic spell Summon True Elemental, which only druids and practitioners of Elemental Magic may cast. There is one for each element, earth, air, water and fire, each level 20 with Will 20, and each will teach or cast the spells of its own element.

Every spirit entity dwells on a spirit plane and must put on a physical body whenever it is called into the prime material plane.
