They typically grow more powerful with age, and several dragons are known for having enough strength to rival the likes of Archons and other similarly powerful beings such dragons include Azhdaha, Dvalin, and Durin. As elemental beings, they have far longer lifespans than mortals and even gods. Vishaps and elemental dragons are born from the elements. A dragon's size is proportional to its strength the immensely powerful Azhdaha, at his full strength, was as large as a mountain range and his size when fought in Beneath the Dragon-Queller is his form after years of erosion Dvalin is also stated to have suddenly grown in both size and power when he reemerged as Stormterror. They typically have physical attributes reminiscent of their associated element for example, the Earth Dragon Azhdaha has rough stone skin befitting of Geo, Dvalin has a much more sleek and svelte appearance befitting of Anemo. Some are quadrupedal, some are serpentine, and some either have wings or none at all. Dragons are a naturally large species of reptilians with varying appearances.
