Run or Serve
Dagon is the leader of the Cult of the Unmortals, and the Mayor of Innsmouth. He is also the modern incarnation of Tamash, an Outer God of Earth. He can grant immortality to those who follow him.
He killed himself beneath Innsmouth when Hastur told him an Unknowable Secret. He collected droplets of every runner’s blood to fuel the summoning of the Elder God.
