Green Dragon

Green dragons were master manipulators who reveled in corrupting lesser creatures and hoarding them like possessions.Green dragons were most notable for the large, waving crest or fin that started at the dragon's nose and ran the entire length of the dragon's body. They also had exceptionally long, slender forked tongues.
These dragons were known to have very bad tempers and a tendency for evil behavior.[6] They loved intrigue and secrets. They put up a front of diplomacy and deceit when dealing with stronger foes, but they revealed their cruel and petty nature when intimidating lesser beings or when gaining the upper hand. They delighted in stalking their enemies and listening in for any information they could gather before moving to attack. Green dragons especially enjoyed corrupting or consuming elves and fey creatures.
Green dragons valued their territory, but only as a means to gain as much power as possible without expending considerable effort. They would sometimes trade safe passage for a worthy item to add to their hoards. Even so, they were extremely cunning and duplicitous foes, and loved double-crossing others. A traveler who stumbled into a green dragon's territory might be able to bribe the dragon for safe passage, but more often than not the dragon would pretend to agree and then attack the unsuspecting offender once their guard was down. Worse, if the traveler impressed the green dragon during its stay, they might start thinking of the newcomer as a prized possession to be corrupted and sculpted to its wil.
Lairs The typical green dragon lair was located underground and was a complex of caves and tunnels, with its main entrance hidden behind a waterfall. The preferred green dragon lair was a cave high up on a cliff, but such locations were usually hard to find and thus only home to the oldest and most powerful green dragons.
Homelands These dragons were typically found to live near woodlands.
