A race of
fish-like
humanoids that lives under the
world's
oceans and
worship Cthulhu,
Dagon, and
Hydra. They are
immortal, though they can be destroyed by violence. They look like
gruesome bipedal frogs, with
warty,
scaly skin,
bulging eyes,
gills, and
webbed and
clawed hands and feet. They can
vocalize a little, but tend to stick to
croaks and
growls; they appear to
communicate with each other through
telepathy.
They normally prefer to
avoid humans, but have been known to
mate with them in order to create human-deep one hybrids.
Hybrids start out looking like
normal people, but as they grow older, they become more and more
fishy in appearance. Eventually, they turn into deep ones completely and
swim out into the ocean to spend
eternity in
adoration of their
blasphemous gods.
