Royal Crimson Dragons are so named due to their massive size and confident, regal bearing. Most of the time they are laid back, ignoring non-prey creatures smaller than themselves, although they will occasionally take fresh kills from other dragons as a reminder of their place in the social order. Although there are few other dragons large enough to pose a threat to Royal Crimsons, they have little tolerance for potential rivals and will fiercely defend their territory from such intruders.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Created in an environment of violence and savagery, lava, blood, and flaming stones, this dragon came from a very competitive spot between the dragons of her kind. Struggles and bloody wars were natural in place where she lived and was born, eggs were easy targets and enemies crushed them mercilessly with frequency, She was the only one of the litter who survived through childhood and because of this her name means "blood diamond". Uru was an adult queen when she was deposed and expelled from her territory and all of her family were killed. She left vowing revenge. In that place were only the strong survived, she was raised to be strong, to survive and to kill without the slightest remorse to keep living. According to that environment known for the endless dragon wars, those who lost were killed or expelled... and few were merciful enough to throw them out.
