Green dragon

Green dragons are master manipulators who revel in corrupting lesser creatures and hoarding them like possessions.

Physical description
Green dragons are most notable for the large, waving crest or fin that starts at the dragon's nose and runs the entire length of the dragon's body. They also have exceptionally long, slender forked tongues.

Breath weapon
Green dragons expel a cone of corrosive chlorine gas.

Personality
These dragons love intrigue and secrets. They put up a front of diplomacy and deceit when dealing with stronger foes, but they reveal their cruel and petty nature when intimidating lesser beings or when gaining the upper hand. They delight in stalking their enemies and listening in for any information they can gather before moving to attack. Green dragons especially enjoy corrupting or consuming elves and fey creatures.

Society
Green dragons value their territory, but only as a means to gain as much power as possible without expending considerable effort. They will sometimes trade safe passage for a worthy item to add to their hoards. Even so, they are extremely cunning and duplicitous foes, and love double-crossing others. A traveler who stumbles into a green dragon's territory may be able to bribe the dragon for safe passage, but more often than not the dragon will pretend to agree and then attack the unsuspecting offender once their guard is down. Worse, if the traveler impresses the green dragon during its stay, they might start thinking of the newcomer as a prized possession to be corrupted and sculpted to its will.

Lair
Green dragons dwell in deep, old-growth forests. The typical green dragon lair will be a complex of caves and tunnels, with its main entrance hidden behind a waterfall. The preferred green dragon lair is a cave high up on a cliff, but such locations are usually hard to find and thus only home to the oldest and most powerful green dragons.

Parenting and development
Green dragons are reasonably good parents, with both mother and father typically staying close to their eggs while they are incubating. Green dragon females either keep their eggs in a solution of acid or bury them in leaves moistened with rainwater. The green wyrmling is easily mistaken for a black, due to their nearly black scales. As the wyrmling matures, its scales become steadily lighter in color until they reach the striking green shade of an adult. The wyrmlings typically stay with both parents until they reach adulthood (approximately 100 years).
