Halla

The halla leap with such grace and beauty as to make horses look like Ferelden dogs.

The halla are a type of horned stag, generally found in elven civilizations. The Dalish do not consider them beasts of burden but rather as noble companions. To get them to accompany a clan, the Dalish elves ask rather than force them to.
No creature is more revered by the Dalish than the halla. No other animal has a god of its own. These white stags are much larger than ordinary deer, and the Dalish halla keepers carve their antlers as they grow, making them curve into intricate designs. In ancient times, these stags bore elven knights into combat.
