(for instance, Dagon and Hydra). The deep ones have
great skill in biology and genetics, and thus can often
control and direct such growth to suit their nefarious
purposes.
Deep ones are also capable of domesticating and
using other types of undersea creatures, particularly
Mythos beings such as shoggoths.

Interaction
The deep ones maintain constant
surveillance and contact with the
surface world near their homes.
Their ultimate purpose is not their
prerogative,

but

determined

by

Cthulhu’s design. They not only
monitor mortal activity for the Great
Old One, but may someday be used
to supplant the mortal realm.
Their

hybridization

and

inbreeding is one important tool
toward that goal, for it allows
them to blend in with mortals.
The hybrids, of course, knowing
they will one day be full deep
ones, are fully supportive of the
deep ones’ goals.
Deep ones are known to
have originated many magic
items, including the medallion
of Y' ha Nthlei, seal of Hydra,
starstone of Mnar, and tiara
of Mnar. They also practice
a

profoundly

dangerous

method of creating twshas
to control shoggoths and
proto-shoggoths.
