Melyngar

Melyngar is a fictional character in Lloyd Alexander's fantasy novel series The Chronicles of Prydain. The prized horse of Prince Gwydion, Melyngar is most visible in the first book in the series, The Book of Three. When Gwydion is presumed dead, the protagonist Taran and his companions attempt to let her lead them home so that they might give High King Math the news of his kinsman's death. Instead, she leads them to the secluded valley belonging to Medwyn, a place which only animals are able to find.

Gwydion, who is later discovered to be alive, rewards Taran for his courage by giving him Melynlas, a gray stallion who was Melyngar's own foal.
