As they competed with other types of dragon, Longititanes found an advantageous niche as mostly subterranean hunters, but eventually diversified into the two main lineages. These dragons are characterized by the almost complete loss of limbs and general elongation of the body, giving rise to predators somewhat similar to snakes, evolved by hunting prey among tunnels and crevices.
From basal Longititanes evolved the order Terraserpentes, also known as Wyrms. These dragons are adapted to life on land, and have a much greater lateral flexibility that allows them to move without limbs. Wyrms vary a lot in size, specially compared to other types of dragons such as Drakes. They are exclusive to the Old World and have found great success all across the region, finding great success in hotter environments of Europe, Asia and Northern Africa.
Wyrms are characterized by the almost complete loss of their limbs, although these are more noticeable in some species. Given their subterranean lifestyle, most Wyrms have lost all of their feathers, have harder and streamlined scales, strong lateral muscles and a hard, pointed nose to help them move along the substrate. Their coloration helps them blend into their environment, but will at times be used to intimidate competitors or attract mates, helped by crests and horns seen in non-subterranean Wyrms.
Living and hunting habits of these dragons can be very varied, as are the environments they inhabit around the world. Wyrms tend to hold domain over specific territories, and will fiercely defend it against intruders. Wyrm parental care is quite varied, with some species caring for their young and others leaving them to fend for themselves, and some even allowing their adult offspring to share their territory.
Apep / Apophis
Psammoserpens luxinimicus
Habitat: Egypt.
Possibly the biggest Wyrm ever to exist. During the day it lays belly up, half submerged in the sand and hidden by its light tan coloration. At night, it awakens and hunts unseen thanks to the dark blue color of its back, silently digging towards any possible source of noise or light in its environment. The Apep is very territorial, and will often patrol its territory, roaring and hissing loudly to keep other predators, as well as other Apep, at bay. When two Apep clash, the sound of their fangs and scales violently clashing in the dead of night sounds as loud as thunder.
