Monster Name: Drake
Drakes represent the middle stage of a dragon's life cycle. They have developed from wurms, but have not reached (and may never reach) the dragon stage. Drakes will aggressively defend their territory and seek to expand it as much as possible. Drakes are actively hostile against other drakes, who represent competition for scarce resources.
Their coloration reflects the territory they have claimed. A drake living in a swamp, for instance, may be shades of green, brown and black, and possess nictating membrances, a flat snout, and raised nostriles. While all drakes can breathe fire, many also develop alternate breath attacks, incorporating other elements.
