The Blood-Crown Hook-Horn is a fierce-looking, herbivorous wyvern native to the jungles of Northern Shangrila. It is an aggressive animal, tempered by the presence of fierce predators that prowl the forest's undergrowth. If faced by a threat, it will respond by sinking its sharp claws into the hide of the attacker and slamming it with its massive tail. Surprisingly, it does not use its horns to attack.

The red-colored heads and long, curved horns are characteristic of the males of this species and serve as a display structure. The longer the horns and the more vivid the red coloration, the more appealing the male is to the female.

Blood-Crowns mate right at the tail-end of the dry season, shortly before the rains come. At that time, males will perform loud, bellowing calls to attract as many females as possible and sire as many young as possible. If two males meet, they will attempt to outperform one another. The winner of such a bout is determined by who is the biggest, loudest, and who has the most vivid red head.
In the case of two equally matched males, bloodshed is inevitable. If they can't intimidate one another, the males will try to break each other's horns, thus ruining the rival's chances for a successful mating.

When the rains come, females will seek out elevated and dry areas (typically under the cover of old trees) to lay 5 to 10 eggs, which will then hatch by the end of the rainy season. By then, all the plants will have bloomed and produced fruit, which is a vital element of the hatchlings' diet.
The young will remain with their mother for 5 years, learning the basics of survival in the dense forest. By the time they are 10 years old, they will be fully matured and ready to start the cycle anew.
