Green dragons

The green dragon is a belligerent creature and master of intrigue, politics, and backbiting. He is cruel. He prefers forests—the older and bigger the trees, the better. Instead of being overtly aggressive, he prefers to concoct elaborat schemes to gain power or wealth with as little effort as possible. He may make his lair behind a waterfall or near a lake, pond, or stream that provides a submerged entrance. The closer one gets to his lair, the darker the woods become. Evil hangs in the air, mingling with the forest scents to produce foul odors.
