The Valkirtani Dragon originally belonged to another land far across the sea. Then a long time ago a group of them made their way over and settled in Laramidia with the native Tannin. The rest of them are still probably in their homeland and may have all but forgotten the ones who crossed the sea.

The Valkirtani have a unique and nigh limitlessly powerful ability of their own that allows them to tap into the ambient magic that permeates all things, and change the nature of physical matter to enchant the material to exhibit a different unnatural behavior. This could be made permanent effect, or it could be temporary allowing them to create magical objects or Spell-like Phenomenon, but this ability takes a long time to learn and even longer to master especially if you want to add more complex enchantment. First you need to know how something is meant to work before you go changing anything, and then you need to understand the new property you are trying to give the object and how it will effect reality, if you add too many things onto a single object carelessly they could make a contradiction and destroy the whole thing or make something entirely unrecognizable and unrecoverable from it's original form.

The Valkirtani put a strong emphasis on education and rules in to teach all of their kind how to use this ability properly so they don't end up creating something disastrous by mistake, but also their power has made many of them curious to master and discover every possibility of their powers and try things that have not been done before, though this boundless desire to discover has led to their downfall in the past.

In Laramidia the Settler Valkirtani once had a great magical empire that enslaved the native Tannin as a labor force so they could focus more on greater magical achievement, and their hierarchy was a sort of Magic based meritocracy based on whoever was able to prove they were the greatest mage by being able to innovate and create new magical discoveries.

They pushed the limits experimenting on everything they could think of and even disregarded some morality for further discovery. This would eventually prove to be their undoing as the push to drive curiosity past all boundaries would create one among them who disregarded the idea of boundaries to prove he was the greatest mage of all and should be made their king. Disgusted by the twisted reflection of their own faults they rejected him and cast away, only to realize too late the horrible mistake they had made.
He turned to the Tannin Rebels and helped lead their slave revolts and revolution against the Valkirtani Empire, leading to a genocide of the Laramidian Valkirtani. The survivors who were left found places to lay low in remote locations of Laramidia and some of them may even have fled to Appalachia, meanwhile their traitor faded into the mist of history.

In the modern Era none of the Valkirtani in Laramidia who were once a part of the atrocities committed against the Tannin live today, but they are still persecuted and hunted by most of the modern Tannin population. Some have found safety in small Tannin populations but are slowly nearing extinction as more and more Valkirtani hybridize into the Tannin population. Some Valkirtani try to maintain a strict separation from the Tannin and live in remote places to avoid being bothered or killed.
