Unicorn

A unicorn was a mysterious and majestic magical beast resembling a horse with a horn protruding from its forehead. Unicorns were often sent as servants of Corellon Larethian, Eldath, Isis, Labelas Enoreth, Lurue, Mielikki, Mystra, Rillifane Rallathil, Sheela Peryroyl, Silvanus, Solonor Thelandira, and Tymora to aid their worshipers.

Description
A unicorn resembled a horse with a white coat, mane, and tail. However, it had a number of traits that distinguished it from a horse, including cloven hooves and a long ivory-colored horn that protruded from its forehead. Males had a white beard.

Unicorns were not subject to poison, death magic, or charm spells.

Society
Unicorns dwelt deep within their forests and shunned most creatures, only conferring with fey such as pixies, dryads, and sprites. They usually showed themselves only in defense of their forests. They scratched glyphs into the bark of trees in the areas under their protection.

Unicorns mated for life.

Unicorns that rested at the Place of the Unicorn, sacred to the unicorn goddess Lurue, in the Sword Mountains were healed of all injury and disease.

Combat
Unicorns were able to sense evil nearby and radiate an aura which protected them from most evil spells. A touch of the unicorn's horn could both heal wounds and cure poison. Unicorns could fey step (teleport) to a nearby location. Unicorns attacked primarily by impaling foes on their horns, although they could also use their hooves as weapons.

Locations
At least 100 unicorns could be found in the High Forest, as well as a few down through the Unicorn Run. Unicorns were most likely to be seen near the Sisters waterfalls, where seeing them and the moon rise above the cliffs were seen as a sign of good fortune from the goddess Mielikki. Other locations home to unicorns included the Forgotten Forest.

History
A cavalry of 50-100 "unicornriders" existed in ancient Cormanthyr.

During the Shoon Dynasty, rulers experimented on unicorns in an attempt to discover the secrets of eternal youth. A herd of unicorns used to inhabit Shilmista before they and the elves that tended them were slaughtered in 355 DR by Necroqysar Shoon VII for use in the Tome of the Unicorn and the Staff of Shoon.

Ecology
Unicorn horns were reputed to have magical and healing properties. They could be used in the production of antidotes and healing potions. They could be sold to alchemists for thousands of gold pieces. However, there were many people in the Realms, particularly followers of Mielikki and Lurue, who were willing to punish slayers of unicorns with death.
