The
Great Seal actually consists of four seals, three lesser and one
greater, but only the Great Seal is located in Gallowspire. The three
lesser seals are watched over by the victors of the Shining Crusade,
and are intended to support the magic of the greater.
The
lesser seals were created at the same time as the Great Seal. The
high-priest of Aroden, Narthoc, ordered each of the parties that took
part in the Shining Crusade (Taldor, the dwarves of the Kingdom of
Kraggodan, and the Knights of Ozem) to take them far away from
Ustalav, so that the Great Seal could never be opened
The
magic of the Great Seal is extremely powerful. The only way for
someone to breach the magic is to locate and disable all three of the
lesser seals.
