Quest Text Something's scribbled inside the shield of the lion statue.
Given that some ancient language is mixed in it, it must have been written a long time ago.
Below the text is a spellbound seal that contains the magic spell
that proves the identity of Cartian NPC Knowledge the Great Sorceress.

Summary The lineage of black magic goes back
as far as the Book of the Ancient.
I am Cartian NPC Knowledge, the Great Sorceress, and I shall find the prepared sorcerers
who managed to discover this seal.
You shall head to Tarif, my hometown.
