This is not any particular
set of volumes,
but one which is personal to the devotee
and his/her path,
patron deity,
etc.
Any particular devotee's records may be called by such a title,
but it is generally reserved for those records
which have been scribed or dictated by adepts
of such attainment
so as to themselves be called eternal.
The Grimoires of the Eternal Dreamers contain
notes, designs, etc,
both of a theoretical and of a practical nature,
and records the devotee's journey to adeptship
and beyond.
Often containing dictates given from on high,
visions of far away places,
secret formulae,
personal hymns and rites,
etc,
these volumes contain knowledge which is
occult and forbidden to the masses during this Aeon.
The volumes penned by the most learned adepts,
indeed take on a sacred and even mythological character,
occasionally written in enciphered, obscure languages.
