The original work is purported to have
been written in the elven tongue and
protected by spells that obscure the meaning
of its content. Some of the copies are
rumored to contain explosive runes or
even symbols. Other rumors tell of poisoned
needles in the locks and curses
inscribed on certain pages. Little else is
known of the tome, but for this excerpt
from Encyclopedia Rothari on the subject
of Famous Magical Works:

"I have been informed by Haliman the
Elder that he has succeeded in deciphering
five of the spells, though they are of lesser
import than he had hoped. The first,
which he calls Odeen’s magic cloud,
appears to be a spell to evoke small clouds
of various color and effect. The second,
Odeen’s impenetrable lock, is a form of,
locking spell. The third, Odeen’s magic
tailor, is a spell to alter garments to fit.
The fourth, Odeen’s secret word, is a spell
to render writing unreadable until a certain
word is spoken. The fifth, Odeen’s 
sounding stick, is a spell to find faults in
stone by tapping with a stick. Haliman
reports that the most difficult of these
spells is no more intricate than a fear
spell, but that he believes the most cogent
spells in the work are more cleverly
concealed."

The tome is certain to contain many
more puissant and perilous spells, but
none of the copies are available, for their
owners are fiercely jealous of them.

Generally, finding the secret words that
guard the volumes will be as difficult as
finding the word of command for a magical
item, so lejend lore or some other such
spell must be employed. Sages would be
quite unlikely to know the secret words,
much less to divulge them. Each spell in a
copy of The Spells of Odeen would be
protected by at least a secret word, and
the more powerful spells would be protected
by other means as well. It is up to
the DM to decide which spells
should be included in a copy of this work
if it is found. It should not include all of
the five spells listed in this article, and
should include a number of more powerful
spells, the nature of which is left to the
DM's discretion. About half the spells
should be incomplete, not all of them
noticeably so. This way, more than one
copy of the tome must be consulted in
order to gain all relevant knowledge.
