Gronnling

Gronnlings are adolescent gronn. Once "befriended", a gronnling will happily carry its rider to their death. Gronnling scales are more like stones than true scales, as the brutes themselves seem to be part stone. Alchemists have been known to show an interest in digging up gronnling bones for research purposes.
