Lizardfolk

Lizardfolk are semi-aquatic reptilian humanoids. Their skin is covered in scales and varied in color from dark green through to shades of brown and gray. Taller than humans and powerfully built, lizardfolk are often between 6 and 7 feet tall and weighed between 200 and 250 pounds. Lizardfolk have non-prehensile muscular tails that grew to three or four feet in length, and these were used for balance. They also have sharp claws and teeth. Although non-reptilians struggle to tell the difference between males and females, lizardfolk can easily distinguish themselves. Lizardfolk have to keep their skin relatively moist and need to wet their bodies regularly if they are in dry climates. For this reason they are particularly fearful of desert landscapes.
Lizardfolk are strong and hardy beings, and their thick scaly hides protects against attacks. They can hold their breaths far longer than humans can, up to twice as long as an equivalent human. This ability enables them to operate underwater in their marshy homes. The lizardfolk's tails aid them in keeping their balance and in leaping, and make them particularly gifted swimmers. Lizardfolk are also noted to have darkvision.
Lizardfolk have no interest in money or jewels. They also do not much value accumulating knowledge if it is not practically useful. They largely value things based on whether or not it was good to eat. If it is, it quickly gets their attention; if not, it is ignored. Lizardfolk can often become distracted at the appearance of food, even if they are in combat. They are easier to parley with after a meal, and a hungry lizardfolk is completely obstreperous.
Lizardfolk can be highly dangerous when provoked. However, they are not inherently evil; they are simply savage and have a hard time fitting in with the civilized world. Those that ventured into towns or cities are often alarmed, frightened, or offended by the environment. Few try to adapt, let alone assimilate into other societies. Instead, they feel their part is to learn about "softskin" ways and in turn show them how "real people" live.
Lizardfolk females lay clutches of eggs, from which their young hatch. The eggs are kept well protected in the tribe's lair. The life of a hatchling is especially hard. Lizardfolk reach maturity within five years of hatching. As lizardfolk aged, their bodies slow down. Most lizardfolk over the age of 60 spend their days laying on warm rocks in the sun. Although lizardfolk aged much the same and have a similar lifespan to humans—the oldest reach 80 years of age—it is rare for lizardfolk males to grow old as they usually died in combat long before.
