Oneiric Vaults are a form of long-life sensory
deprivation casket. Utilised by astralsophists to
expand one's own higher understanding and
ability for the astral arts, suspended in a
self-induced state of meditation.

The occupant is placed within a massive sculpted
idol, base upon the designs of ancient antiquity.
Once interned the great stone jar is flooded with
the dense, clouded, oxygen-rich amniotic fluid of a
large amphibious cephalic predator.

The peculiar brine has psychedelic properties when
imbibed. Full-body submergence results in a dream
state of fathomless depths. The fluid can sustain the
slumbering for months at a time, allowing one to
unburden their mind from body and glimpse the
wonders of the cosmos.

Astral projection achieved in this manner is
effective but limits one's own grip on reality and
terrestrial existence. The higher powers afforded to
the oneiric interned, combined with their detached
suggestible mental state, makes them viable as
potential siege machines of celestial fury.
