Graphorn

The Graphorn is a dangerous aggressive magical creature, native to the mountains of Europe.

Nature
The graphorn is large and hump-backed, with greyish-purple skin tougher than dragons. It can repel most spells, has two golden horns, and walks on large four-thumbed feet.

Uses
Its Horn is a highly prized potion ingredient, used in potions like the Antidote to Uncommon Poisons. Graphorns are sometimes used as mounts by Mountain Trolls, but the Graphorn does not like it - it is more common to see mountain trolls covered in scars from a Graphorn.

In the Study of Ancient Runes, the Graphorn's two sharp horns are used to represent the number two.
