The grynn was a large species of saber-tooth cat and one of the most ferocious predators to stalk the plains of northern Dove and southern Frauji. Fully grown grynns had a body length over over 2 meters, with golden and white fur often streaked with dark olive patterns. The mouth of the grynn reached beyond their cheek and all the way to the shoulder, full of serrated, shark-like teeth that gave the species its name. This incredibly unique jaw structure allowed the grynn to maintain multiple points of contact simultaneously while its prey struggled. Most grynn, who lived predominantly in isolation, hunted for animals that grazed the plains such as kûmap-flol while staying clear of members of the 44 Peoples. However, starving individuals would readily view isolated travelers as prey.
The grynn were one the first adversaries early Eavons faced when settling from Trinity and into the rest of Eranosia. However, the grynn offered a formidable challenge that allowed the Eavons to adapt and evolve culturally at a rapid pace. The use of sharp stones as weapons, traveling as a group, and the beginning of hunter-gathering society can be attributed to early Eavon responses to grynn. As a result, once Eavon society transformed into the Holy Eavonian Confederation, the grynn became a symbol of persistence and adversity in the face of conflict, with many noble houses of Dove, Frauji and Pahru adopting the image of the grynn into their family crest. Despite the image of the grynn remaining stable, the wild population did not as a result of urban expansion, with a majority of the living individuals kept as zoo animals or sold in the exotic pet trade. Once these urban centers were destroyed during the Solstice War, the grynn population began to climb back up.
