Dragons born from Polvorón and Vita are always born when the magics of the world are the purest, untainted by any and all progress dragonkind has done throughout the years: on the day of Sornieth (Earth Day).

Whilst their general magics is the same as their half-siblings's, their earth magic is the strongest, but they also have another power that is exclusive to them. These offspring have the ability to purify anything they touch, be it cleansing a plague from a dragon, to removing any and all pollution from the surrounding water. Another facet of this magic is the ability to reverse time on something that has been changed by unnatural technology, returning it to its original form.

One would think this makes them averted to mechanical creations, but they are only critical of those that purposely bring danger to nature. While they are most comfortable in natural environments, they will not oppose to living with those who are interested in the technological side of life. In fact, they aren't against the idea of teaming up with them to make sure it's earth-friendly.
