The Twilight Unicorn's striking black coloration stands in dark contrast to its white counterpart. Its hooves and horn are a gleaming gold, and red roses are entwined in its mane. The idea of a black Unicorn has existed as far back as Fifth Century B.C. In his book on the wildlife of India, Ctesias wrote that Unicorns could be white, red, or black. Standing 4 ½ inches tall, the Twilight Unicorn measures 5 ½ inches from nose to tail.
