Alright, about those antlers…
The island that the clan resides on is situated atop a myriad of leyline intersections, the majority of which are located beneath the main settlement. These intersections cause huge amounts of magic to seep up to the surface, tainting the plant and animal life. Crystals grow naturally from the ground as well as particularly magic-rich trees and the like.
So, it goes without saying that as beings held together solely by magic and completely dependent on it for survival, dragons would be prone to the same phenomena. Adult dragons are not liable to have crystalline growths unless they spent an exuberant amount of time near the most concentrated areas of magic dispersal. However, the same cannot be said of children born on the island. As they are in a period of time during which their bodies undergo immense physical changes and growth, the formation of crystals is far more likely to appear in a matter of years as opposed to decades.
Another area of concentrated leyline intersections is located in and around the Stargrove Orchards. Crystals grow naturally from magic vents in the ground alongside the trees in the orchards. Only on very rare occasions have residents of the nearby villages been victim of crystalline growths emerging from their limbs and/or extremities. However, one of the orchard tenders, T’lekah, has consistently worked with the trees while pregnant and tending to her children. As a result, they have developed crystalline antlers as opposed to the typical sets made of bone and marrow.
The first signs of crystal growth begin after infancy and in the toddler years. The growth begins at the base of the children’s antlers and slowly overtakes the established bone structures, eventually completely replacing the tissue with concentrated magic, much like bone matter is replaced with minerals during fossilization. By the time that a child has fully matured, their antlers are completely overtaken by crystal, making for a dazzling pair of appendages. The crystal growths also appear on the children’s arms, but are far smaller and easy to pick away during bathing.
As the crystalline structure would continue to grow and spread as the children age, threatening to overtake their skull and damage their health, small, delicate runes have been inscribed along their antlers. These runes contain future growth to the preexisting crystal, rather than allowing it to run rampant about their bodies. As such, their antlers continue to grow as they age and their bodies are naturally exposed to Sornieth’s latent magic for longer periods of time. However, crystals cease to appear on other elements of their anatomy, saving them from horribly painful debilitating circumstances later in life. Should one of their antlers be damaged or broken, the lost element would return eventually, but never to the full size and extent as before.
