When magic rises into a physical form, it doesn’t always take the more commonly seen human-like form. For whatever reason it may choose a cute and friendly form, like this rock dog example. Naturally, the villagers nearby have called him Rog.
These stony beings rarely take the shape of wild animals, instead favouring the more domestic sorts such as cats, horses, and dogs. If there is a reason for this, it’s not an overly clear one. Perhaps they just take the forms more commonly seen as familiars, but why?
Regardless, Rog is very popular with his local children, and has fetched many a stick without complaint.
