Rock Dragons

Description
Rock Dragons have scales that vary in shades of grey. Their underscales are often grey, brown, white or even red. Very rarely there will be a dragon born with oddly colored scales, such as the colors listed above. More on that later.

Rock Dragons are sturdily built with strong legs and large wings. Their snouts are short and flat and most of them are super strong as a tribal trait. Eyes can vary from any shade a rock, agate, or gem is.

Their ears and sense of smell and sight are more advanced because the tribe used to live in caves, so they has to be able to hear rocks shifting in case of a cave in, and smell if there is a natural gas nearby. The also can see in the dark.

Diet
Rock Dragons eat meat like mountain goats and rabbits, but they also eat plants that grow on the mountain. They will occasionally trade with other tribes for things like fish or camels.

Rock Dragons have a unique way of hunting. The will dig a hole going straight down into the food chambers, then cover the holes with a woven net, then carefully balance different types of food on top, depending on what food chamber it is over.

To catch birds they create special nests, and when the birds lay eggs, the Rock Dragons drop the nets positioned over the special nests and eat both the birds and the eggs.

Rock Dragons only eat their food cooked, and will turn down anything raw, except fruits and vegetables.

Seeing in the dark
Rock Dragons developed the ability to see in the dark when their tribe moved into caves and were too afraid to light torches, because they didn't want to explode the natural gases that formed in the caves.

Sensitive Hearing
Rock Dragons developed sensitive hearing when their tribe moved into caves and needed to hear rocks shifting to avoid cave-ins and underground rivers.

Enhanced Smell
Rock Dragons developed the enhanced smell when their tribe moved into caves and needed to locate the natural gases that formed in the caves.

Marriage
Marriage wasn't really a thing for Rock Dragons until it became very popular in Landfall City. Before that you would take a mate.

Inter-tribal Relationships
Inter-tribal relationships depended on the queen. Queen Mineral despised and forbade it while her daughter Queen Stone was neutral about it.

Same-Sex Relationships
Depended on the queen. Mineral despised it while Stone was neutral about it. Mineral's great-great-great-great-great-grandmother encouraged it, and after the death of the king, took a female dragon as a mate. (This was before marriage was a thing)

Breeding restrictions
This would depend on many factors, such as queen and population size. Queen Mineral required at least three babies, while Queen Stone lifted the ban. A bigger population could mean restricting the amount of babies each family could have, while a smaller population would do the opposite, requiring a certain amount.

Military
10,000 soldiers split into 10 armies        1000+ Officers

Oddly Colored Rock Dragons
Oddly colored dragons are the dragons who have scales that are brown, white, black, and even green or orange scales. They are treated differently depending on the queen. Queen Stone treats them as equals, while her mother, Queen Mineral saw them as a threat and had them either killed, imprisoned or banished. One of the other queens, Queen Slab, saw them as gods and took them from their families almost as soon as they hatched. She kept them locked away to be worshiped, and their families were payed a large sum of money as compensation.
