The Lesser Key of Solomon describes the demon Valak (also spelled Valac, Ualac, Valu, Volac, Doolas, Volach) as the Grand President of Hell who commands legions of demonic minions. It states the following:

The Sixty-second Spirit is Volac, or Valak, or Valu. He is a President Mighty and Great, and appeareth like a Child with Angel's Wings, riding on a Two-headed Dragon. His Office is to give True Answers of Hidden Treasures, and to tell where Serpents may be seen. The which he will bring unto the Exorciser without any Force or Strength being by him employed. He governeth 38 Legions of Spirits, and his Seal is thus.
