Emerald dragon

Emerald dragons were gem dragons who were inquisitive and often more knowledgeable than most sages.

Personality
They tended to be paranoid and distrustful of visitors, and their lairs often had many traps.

Combat
Emerald dragons could breath a cone of sonic energy. They might also generate a cloud of fog to blind opponents.

Society
Emerald dragons preferred to live underground in areas close to civilization, although they seldom made their presence known, making cones of inactive volcanoes the favored spot for their lairs.
