Carnivorous birds of prey with large heads, heavy beaks and broad long wings.
Rocs have a wingspan that ranges from 10 up to 30 canes (meters). They are considered to be trove-bound, meaning they have no natural means of propulsion that would aid their flight outside the gravity field of a trove.
Despite being smaller size than many Wyverns, their heavy built and muscular bodies make them the avian apex predator of any trove they inhabit. They are solitary hunters and they have been observed to mate for life. A roc’s talons will usually be hard enough to pierce through any non-magnetized hull, turning the rocs into a severe aviation hazard.
