This unusually heavy scroll consists of a rather long sheet of supple, impossible-to-tear parchment wound between two rods.
When using the anathema archive to cast spells, the user can either simply open it (in which case it randomly opens to one of the new Thassilonian spells in Mokmurian’s Spellbook) or the user can attempt to force the anathema archive to open to a specific spell from that list or to any arcane spell she knows how to cast. Doing so requires a Spellcraft check (DC = 20 + double spell level)—failure indicates the archive opens to a random Thassilonian spell as above. Whatever spell the anathema archive is opened to, the user may cast that spell from the scroll as if she were casting a spell from a normal scroll, save that the spell is not consumed from the anathema archive upon being cast.
When used for research, the anathema archive grants a +10 insight bonus into any one Knowledge check associated with sinister or frightening ancient topics (subject to the GM’s discretion). This allows a character to make the Knowledge skill check untrained.
Each time a character uses the anathema archive, her mind becomes increasingly haunted and unhinged. Upon using the archive, the user must make a Will save (based on the total number of times the user has used the anathema archive). Failure results in bad things happening.
The anathema archive closes automatically each time it is used, and cannot be opened again for 24 hours by any force.
When the anathema archive is opened, it presents a tangle of Thassilonian runes to the observer. Each time the scroll is unfurled, the runes are in a different order, the contents of the archive shifting according to the user’s state of mind and desires each time it is used. The archive itself can be used for two purposes: to cast ancient spells and to divulge lore about hateful secrets and hidden horrors.
