Life on Casarok takes many different forms. The intelligent species are divided into three races, while the rest of sentient life has their own set of three classifications.

The Anthros are the most common and diverse race of intelligent creatures in Casarok. Most species that make up this race correspond to a species of animal found on Earth; however, there are some species native only to Casarok.

The Aspects are the intelligent race of Casarok created to be avatars of the gods and goddesses. Each species of the Aspect race is in the form of a mythical creature that matches their matron or patron deity. Thus, their magic aligns more closely with their deity than the other races.

The Draconic race is the least common and diverse of Casarok's three intelligent races. There are only six known species, each one descended from a type of primordial dragon. They have a strict set of skills passed down to them by the gods and goddesses of Casarok and are unable to learn spells outside this range.

Feral is the classification for all non-magical non-intelligent creatures that naturally evolved from the primordial beings of the Creation Era. Many feral species are docile and capable of domestication. Others are hunted for meat, scales, hide, and other resources.

Monster is the classification for all creatures that evolved from primordial being through the planet's magic. Most of them are non-intelligent and generally hostile or dangerous. They can be hunted for meat, defense, or sport. In more modern times, magical wards keep monsters out of populated areas.

Floradon is the classification for all highly evolved plant-based life in Casarok. They are the accidental creations of the god of time, Tempatrius, and the goddess of nature, Domathair. All species are magical in nature with some more capable of wielding magic than others. As such, some species can be domesticated and kept as pets while others are very dangerous. Those floradons that are not poisonous can be hunted for food.
