The Morrígan
The Morrígan is often considered a triple goddess, but this triple nature is ambiguous and inconsistent. These triple appearances are partially due to the Celtic significance of threeness. Sometimes she appears as one of three sisters, the daughters of Ernmas: Morrígan, Badb and Macha. Sometimes the trinity consists of Badb, Macha and Anand, collectively known as the "Morrígna". Occasionally, Nemain or Fea appear in the various combinations. However, the Morrígan can also appear alone, and her name is sometimes used interchangeably with Badb.
