Unicorns are golden-white, horse-shaped Otherworld creatures with cloven hooves and a single horn in the centre of their foreheads. The few sightings recorded suggest that the hooves and horn vary in colour from individual to individual. They are known to be territorial, solitary and extremely vicious. As with dragons, their spirit form is considered to be very human like.
It is likely that their looks and behaviour influenced the European version of the unicorn myth although it is unlikely that they are the initial seed about which the majority of the folklore has been built. Otherworld unicorns’ opinions on virginity and other virtues is unknown, despite Edmund I’s legend, and there is little evidence that their horns have healing powers. While still connected to their owners, in fact, the evidence suggests that horns are quite deadly.
Sir Theodore Mortimer-Warren suggested in his book, The Founding Of A Nation, that the Lady Alison who married Roger Mortimer, Edmund I’s younger brother, was actually a unicorn in her spirit form living in the mortal realm (see The Animal Wife motif). This wild assumption is based on the most fashionable spelling of her name at the time, Lady Alicern, combined with the infamous unicorn vanishing from the written record at a similar time. Mortimer-Warren went on to erroneously suggest that this was the source of the Dukes of March‘s second sight.
