On the Eversorix
The Eversorix is indeed a mighty predator: Over three meters in height. Lethally sharp claws nearly a meter in length. And a deadly predatory instinct.
The Eversorices, having grown into such large and effective killing machines, no longer need to hunt in groups. They will eat- essentially- anything. Prey of all sizes, from arboreal Kalavalions (whose Fanel and Tranel homes are frequently not high enough to provide refuge) to lumbering Plutonoduplers, to their own smaller predatory cousins. Eversorices will happily scavenge anything they find, and will even eat plants when nutritionally or starvationally necessary. All of these foods are processed in the Eversorices' complex gut, which has various specializations to deal with this highly varied diet.
Structurally, the Eversorices have advanced significantly from their ancestors. A secondary skeleton within them has provided more anchor points for a more complex musculature. The hybrid circulatory system of the Falcirices and their predecessors has continued to develop in these giants- a system of 'hearts' in the extremities pumps blood through the outer regions of the creature, then back into the animal's core, where it is refreshed with oxygen from the dorsal lungs.
Being the world's first 'superpredators', the Eversorices have a relatively small population. This is, of course, due to the large hunting area required by each of them. They wander throughout their territories, hunting and scavenging for all sorts of food. While their large size can be a downside, in preventing it from entering the densest forests without being painfully noisy and obvious, it also allows them to go for some time without food, hunt solo and unchallenged, and move with surprising speed.
