Special Abilities
Earth Glide (Ex) A rognak burrower can glide through any sort of natural earth or stone as easily as a fish swims through water. Its burrowing leaves no sign of its passage nor hint at its presence to creatures that don’t possess tremorsense. A move earth spell cast on an area containing a rognak burrower moves it back 30 feet, stunning the creature for 1 round unless it succeeds on a DC 15 Fortitude save.

Rognak burrowers are enormous creatures that dwell beneath the surface of the expansive grasslands and plains. These fearsome creatures are encountered under the control of a more powerful master just as often as they are found in their natural habitats.

The rognak burrower is equally at home on the plains and underground. It is primarily a carnivore, although it is able to live on plants and fungus when presented with a situation where meat is not available. Whether it lives underground or on the plains, the rognak burrower has a den carved into the earth, where it can usually be found when it is not searching for food. Because of their extensive subterranean burrowing, there is a 10% chance of falling into a sinkhole whenever adventurers encounter a rognak burrower. Rognak burrowers are normally found in small groups. It is very rare for any more than six to share the same living space for any length of time. Each member of the species is both male and female, and can be impregnated by any others within the group, though it cannot impregnate itself. After a gestation period of one month, it lays 2d10 eggs, which are hidden away underground, where the young hatch alone. These young often scatter shortly after birth rather than banding together for their mutual protection. They are small creatures when born, but they mature rapidly, reaching their full adult size within a year.

On Porphyra
Rognak burrowers are common on the western and northern edges of the Pinnacle Lands. They are a common nuisance in the Copperton Mine.
