Brute Dragons are among the larger dragon breeds. They prefer to live in solitude or small groups, nesting in high, mountainous regions. The only time they openly seek the company of others is during the mating season, when males will fight for the attention of females. The thunderous crash of Brute Dragons butting horns against each other in competition for mates can be heard nearly a mile away.

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.

Lumigrax is a very possessive dragon, making sure that no other males come anywhere near the females who are around him. Some dragons call him "Loonygrax" because of this, especially because no one knows how many males could surround him just for the sake of mating season, and Lumigrax is crazy if he thinks he can take on any male who challenges him. Despite his obsession with competing against other males, Lumigrax isn't actually one for much companionship.

When he's not being challenged by other males for dominance over the females, Lumigrax, oddly enough, is as relaxed as can be when alone in his cave in the mountains, napping and crafting his own scrolls to later write notes on. His other hobbies are writing music, drawing cave art, reading, and napping.
