|Natural magical beast (dragon)|
Green dragons are highly territorial, and will often view any intrusion into their domain, voluntary or not, as a personal affront. The forests where they dwell and protect are often very old and are not to be tampered with. Green Dragons are the most 'Druidic' of the dragon-kind, favoring the use of natural magic to encourage the life of the trees, animals and plants in their domain.
Some greens have been known to use their 'life magic' to augment or twist the form of some animals within their domain to become better guardians. Many consider the Owlbear to be a product of Green Dragon magic.
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. They smell like chlorine gas.
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.
