Wyrm

Wyrms are huge, limbless dragons that roam the islands of Arvandor. They are rarely seen beasts, and many cultures treat their visiting as a religious or spiritual event. They tend to sleep for long periods in huge caves, carved into mountains with magic.

Appearance
Wyrms can be staggeringly huge, anywhere from 50 to 400 metres long. Their colouration varies by location, but are often either light, cool colours, such as pale blues or whites to be less apparent in the skies, or darker colours that blend in with their mountainous habitats. Despite this preference for blending in with their environments, wyrms with very distinctive bright colouration and/or markings are known to exist.

While wyrms have no real limbs, some wyrms have dorsal fins or fin-like appendages, but these are not present on all. Often a wyrms tail will have some kind of fin, bifurication, or other shape to it. Some wyrms also have a type of exoskeleton covering their backs, which can take the form of upright back plates, or tough, larger scales covering the back. These protect the wyrm while it lays sleeping, as its belly will be hidden against the ground with the back exposed.
