Ecology

Green dragons rule deep old-growth forests, lairing in cave systems concealed by dense canopy. They feed on elves, druids, fey creatures, and any humanoid foolish enough to settle nearby. Their poison breath corrupts the forest itself; trees grow twisted, animals turn cunning and cruel, and wells run faintly bitter. A green's territory can be identified by the unnatural quiet around its lair, where animals have learned to whisper. Druids consider green territory tainted, and many will not enter without ritual cleansing.

Behaviour

Green dragons are master manipulators who view direct combat as inelegant. They build networks of charmed agents, hostage-bargained subordinates, and willingly-corrupted nobles. A green's true hoard is information; it knows every secret of every settlement within fifty miles, and uses this leverage routinely. They take pleasure in turning friends against each other and family lines against themselves, and treat patient corruption as the highest form of art.

Origin

Green eggs are buried beneath ancient trees and absorb arcane essence from the surrounding forest. Wyrmlings begin charming small fey before they can fly, building an early network of unwilling spies. Young greens specialize in deception, often establishing humanoid identities by adolescence. By adulthood, a green typically has corrupted several local courts and is positioned to expand its influence. Greens reproduce rarely but invest heavily in their offspring's psychological education.
