A Unicorn is not unlike a war-horse with it has heavy cloven hooves, but with a single central horn on it's forehead and intelligence. They like to use their horn as a lance when charging the enemy if forced to fight. Unicorns are magical creatures, which tend to dispel magic that is targeted at them. The horn of a Unicorn is said to have great healing powers, which makes it a sought after ingredient.
Thanks to Cristlefir for this information.
A side note from Lanackse-Kanvae: Unicorns are also said to be attracted to pure beings especially when the pure one is lost.
