The greatest failure of the Arch Mage Calypso is his one legacy sought by Emporers, Dragons, and Gods.

This is a wretched tome of oceanic blasphemy; a foul water-stained, bone-white binder of bitter dead-men's secrets and a guide to Nautical Necromancy useful in the hands of the young sea-faring necromancer or the Great Lich Umeen herself.

A vast tome of knowlege that literally gives you the creeps…

A standard book of evil.

An (un)holy book written in ink created from a Shard of the Storm.

It is a personal journal tucked away in an library. It appears as an ordinary journal or diary from the outside and inside. In the spine or binding there is always a tiny strip of metal that other components and symbols are attached. Yet there is more, if you read carefully.

Exerpt from the Introduction:
I know the ultimate weapon. Humans commit folly after folly because they are afraid. Fear was once Humankind's most powerful ally, giving enormous potency to the instinct for suvival. Now, fear has become Humankind's greatest enemy, and such is the obtusemenss of my species that is members do not realize it is the most powerful element of Human existance.

'It is your move.'

It appears to be a very nice holy book of the dominant good faith, the kind that his passed down from generation to generation. The binding is leather and quite plain, but the inside is nicely scribed and occasionally illuminated. A pity that it will lead you down the Path of Darkness the moment you understand its secret.
