Originating from a single species that thrived in ancient times, Xenowyrms have become an incredibly diverse breed whose appearances vary depending on their habitats. Each Xenowyrm subspecies is heavily reliant on the power of different types of mana, making them powerful magic users. Chronos are often considered to be the most elusive of all Xenowyrm subspecies: they live in the darkest and densest forests, far from civilization. They are masters of time magic, allowing them to manipulate the flow of time at will. It is said that Chrono lairs are protected by a field of magic that makes the minutes tick by at a slow pace for any unwanted visitors.

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.

Time to Murder and Create loves his mate, despite her tendency to lift and drop a question on his plate. He hasn't actually committed the crime he was named after nor created much of anything, though he does seem to inspire artists and villains alike. He is a psychotherapist, helping other dragons talk out their issues and relieve trauma. While he is not as emphatic as an arsani would be, he has been known to travel back in time to the event and help in the moment to reduce the emotional impact it caused.

Sometimes, Murder has been known to snark at his mate's frequent questions, often joking that she makes meals of it for dinner—he describes it with phrases such as "'Why' cooked in 'Do you think', with a side order of 'What'!". What bothers him more than her questions is when other dragons ask how he can stand her questions.
