Back to some dinosaur drawings for a moment :P

The Arid Dryus is the largest member of its genus. As the name implies, it inhabits arid planes and scrublands, located towards the center of the Arcadian continent. Much like its cousin, the Green Dryus, it is a fairly skittish animal, always alert and on the lookout for danger.

These dinosaurs can easily reach speeds of over 60 km/h which is more than enough to outrun most predators.
Other, larger herbivores often keep them around as an early warning system. If the flock of dryus starts running, it means that danger is near.

Some people tried domesticating these dinosaurs and using them as mounts, even though the success rate of that has been quite low so far.
