Caros
Caros or carodulas are animals that feed off the lamis in other animals. Most of these animals cannot absorb lamis outside of their bodies, so they have to ingest lamis-filled sources to fulfill their dietary needs. A select few are able to be trained to absorb lamis from outside their bodies, but the training lacks longevity and the animals tend to revert within a cycle.
Gradus
Gradulas or gradus absorb lamis from the ground and plants. Most animals of this kind passively absorb lamis, and only seek out sources before the sunset or after extreme physical exertion. These animals often remain in herds for protection, but also stay near cities to deter predators.
Soferas
Soferas are most commonly gradus, with the rare exception for trainable caros. These animals are paired with Vox citizens who have an excess of Lamis in their bodies. While not the same as the animal's natural diet, through training, the animals learn to adapt their dietary needs to the Lamis from a person. A successful bonding permanently changes the animals body, and they are no longer able to absorb lamis found in the ground and plants.
To the sky
Pennas can be of the caro or gradu kind that spend most of their time in the sky. There are no trees on the Red Plains, so pennas will fly above the clouds to take advantage of air currents that keep them in the air with little to no physical effort. While caros will hunt gradus that call the sky their home, gradu pennas have to land once a sol to feed off the lamis of the land.
