Brother of Sebastian Senegal
Miguel Senegal was killed by his brother Sebastian Senegal 15 years ago. He was involved in a previous ritual of the Cult of the Floating Horror and was turning into a lizard-creature with a third eye – the host of for the Floating Horror. Senegal killed him to stop the ritual (and presumably save his brother from some horrible end). Miguel’s skull sits on a shelf in Senegal’s office.
