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.

Unlike her mate, A Hundred Visions and Revisions has no trouble making and revising plans. In fact, she plans and re-plans so much that it confuses all the dragons around her. Rumor has it that the hundred in her name comes from the number of visions and revisions she makes every minute. She often takes Time for a Hundred In Indecisions along with her when she sets out to preform one of her plans, and only with his insistence does she follow through with only a little revising. Of course, without her to make a decision, Indecisions can't make up his mind.
