The Batter-Horn is a species of terrestrial, flightless wyvern native to the grasslands of Shangrila. These large herbivores get their name from the battering-ram-like horns on their head. If threatened by a predator, they will charge at it, head lowered, and batter the foe with great ferocity.

If they encounter something that isn't an obvious threat (like a human or elf), they will ignore it and move on with their day. They can be rather docile if left unbothered.

Outside of defense, these wyverns sometimes use their horns to upturn fallen logs or boulders in search of tasty herbs and mushrooms.
They do not possess a breath weapon; they rely on their sheer brute strength to get by.

Addendum:
- This species shows sexual dimorphism. While both males and females have sail-like crests on their necks, those of males are much more colorful (most likely used for mating displays).
- Batter-Horn eggs are roughly the size of an American football. Hatchlings born from these eggs need a few weeks before they can confidently walk after their mother. Before that, they have been observed to "toddle" within the nest (researchers noted this behavior as very adorable)

Note: the illustration above features a hatchling that is around 10 days old (they grow fairly fast during the first few months of life)
