For druids, nature exists in a precarious balance. The four elements that make up a world—air, earth, fire, and water—must remain in equilibrium. If one element were to gain power over the others, the world could be destroyed, drawn into one of the elemental planes and broken apart into its component elements. Thus, druids oppose cults of Elemental Evil and others who promote one element to the exclusion of others.

Druids are also concerned with the delicate ecological balance that sustains plant and animal life, and the need for people to live in harmony with nature, not in opposition to it. Druids accept that which is cruel in nature, and they hate that which is unnatural, including aberrations (such as beholders and mind flayers) and undead (such as zombies and vampires). Druids sometimes lead raids against such creatures, especially when the monsters encroach on the druids’ territory.

Druids are often found guarding sacred sites or watching over regions of unspoiled nature. But when a significant danger arises, threatening nature’s balance or the lands they protect, druids take on a more active role in combating the threat, as adventurers.
