Contrary to popular misconception, dragons are in fact variously herbivorous and insectivorous omnivores, while unicorns are facultative carnivores.
Firstly dragons, or more specifically wyverns, are descendant of the Yi genus of the late Jurassic period. Bearing both primitive feathers, and webbed bat-like wings. Somewhat small, the largest living species only reaches the size of condor. They don’t in fact breathe fire, that’s a misconception, but have been known to spread fire like some birds of prey, in order to rush small prey out of hiding, in times of scarce fruit resources.
Unicorns are in fact not horses or goats, but members of Mesonychidae, a group of hoofed mammals that also gave rise to whales. Their superficial similarities to horses is due to evolving to run down their distant relatives over open grasslands. Their horns are in fact hollow structures of keratin, weak, but used for display. As their crushing jaws and strong legs are used to take down prey.
Wyverns and unicorns though inhabiting distinct niches, often fight over breeding territories in forest glades. With unicorns occasionally feeding on injured wyverns.
