Trollgardic Dreadgull Wyvern

The Trollgardic Dreadgull Wyvern (Wyvernis tyrannus), commonly known simply as "Dreadgulls" or "Thursvælgur" (Troll Swallower) in Urmål, is a species of large feathered wyvern native to Trollgard. In the absence of large predators, Wyvernis tyrannus is the apex predator of the west Vastallosi coastline, tackling proportionally larger prey (including horses, wild deer, some species of drake) than other Draconiformes. A Dreadgull wyvern is an unusually intelligent beast, which possesses a fierce hunger for meat, dead or alive. Dreadgull wyvern’s reputation for ferocity and aggression makes it one of the most feared carnivores of the coast and skies in Trollgard.

Aggressively predatory and possessors of an unusually high intelligence, these creatures were little known by sages, but feared by adventurers and spoken of only in hushed tones.

Anatomy
The Dreadgull Wyvern is closely related to the Vastallosi Wyvern, with many similarities and differences. The adult Trollgardic Dreadgull Wyvern has a white head, neck and underparts, dark grey wings and back, red and yellow bill. An adult dreadgull was about 15 ft (4.6 meters) long, with a wingspan of 35 feet. The average dreadgull weighed about 500 pounds

Unlike any of the true dragons, the Dreadgull Wyvern’s physique overall bears a strong resemblance to a marine bird of prey or seagull. W. tyrannus has tooth-like or knob-like extensions of the bill's margin, called "pseudo-teeth," which enable the animal to better grip and grasp slippery prey. According to Myrknir, W. tyrannus 's teeth "don’t have enamel, they don’t grow in sockets, and they aren’t lost and replaced throughout the creature’s life span."

They have a hand on each arm that is partly detached from the wing (similar to bats' thumbs), with two long fingers and a thumb which are each equipped with long claws.

This one of is the largest wyvern in the world, considerably larger than the Vastallosi Wyvern. Only a few other wyverns, including The Daelryan Wyvern and Lesser Wyvern (Wyvernis communis), come close to matching this species' size. Trollgardic Dreadgull Wyvern is bulky and imposing in appearance with a large, powerful bill.They produce a stomach oil made up of wax esters and triglycerides. This can be sprayed out of their mouths as a defence against predators, dissolving any organic tissue that the venom came into contact with. a direct to the eyes i seriously debilitating l as it instantly blinded its victim with permanent effects. Even a glancing blow could cause severe burns.

Ecology and Habitats
Due to its large size in an environment otherwise dominated by ungulates, canines, and birds of prey, with no large hypercarnivorous draciformes in the region, the Dreadgull Wyvern fill the niche of an apex predator in the West Vastallosi ecosystem. The robust anatomy of Wyvernis tyrannus suggests that it tackle larger prey than other wyverns, including animals too large to swallow whole; similarly, some storks (particularly the marabou stork and the jabiru) are known to attack and kill large prey such as flamingoes, and occasionally children, with their beaks. Meanwhile, other local wyvern like Wyvernis vastallosus instead feed on small prey, including Common Ocelots (Leopardus pardalis) and Jungle Hares (Lepus kawalapuenis).

Dreadgull Wyverns can be both solitary and group animals. They did not have a strong odor, although their lairs often could be tracked by following the smell of their recent kills.

Kamigawan Sky Serpent s, Dracadian Highland Drake "Cliodrake" (Microdracus cliovus), Galínian Roc, and other Dreadgull Wyverns were a Dreadull Wyverns greatest territorial rivals.

Dietary Needs and Habits
Dreadgulls are opportunistic feeders, apex predators, and are very curious. They will investigate any small organism they encounter and will readily eat almost anything that they can swallow. they are highly predatory and frequently hunt and kill any prey smaller than themselves, behaving much like a raptor. Lacking the razor-sharp talons and curved, serrated teeth of other wyverns, the Dreadgull Wyvern relies on aggression, physical strength, a tearing beak and endurance when hunting.

Most foods are swallowed whole, including most fish and even some Dracadian Highland Drakes (Microdracus cliovus). When foods are too large to be swallowed at once, they will sometimes be shaken in the bill until they fall apart into pieces. When capturing Tortoses or other hard-surfaced foods such as Vastallos Murder Crabs, eggs or armored humanoids, they will fly into the air with it and drop it on rocks or hard earth to crack it open. Unlike most other wyverns, Dreadgull Wyverns will readily consume carrion aand have developed the ability to consume infected, poisoned or rotting meat safely. They are skilled kleptoparasites who will readily pirate fish and other prey captured by other birds and dominate over other gulls when they encounter them.

Unlike most other wyverns Dreadgull Wyverns are carrion eaters and have developed the ability to consume infected, poisoned or rotting meat safely.However, they would hunt on live prey if other sources of food were sparce. Sea gulls ate a wide variety of food including carrion, fish, snails, worms, and even some vegetables like turnips, though their most preferred food was fish.
