'Cave Grawla' encompasses a wide range of Grawla that share similar characteristics suited for cave dwelling.

They are typically found underground, living inside sprawling cave networks that the Grawla have used and expanded upon for their recorded history.

Their tendencies to keep to themselves has led to generally more structured societies, which limit their interaction with other Grawla. Similarly their underground nature limits their interaction with the surface. This has allowed the Cave Grawla to be more predisposed to surviving apocalyptic extinction level events that have scoured the surface of their homeworld.
