The Librarian may only be Activated if at least one enemy Faction has an Overdue Library Tome. The Librarian is Activated when a player spends a Silence Token and places the Librarian into any Area containing at least one Unit from an enemy Faction with an Overdue Library Tome. The Activating player then rolls the Agony die; as with the Custodian, if the Librarian stays in the same Area without Moving, add +1 to the Agony die’s final total.
If there is more than one enemy Faction in the Area with an Overdue Tome, the Activating player divides up the Agony die’s total between them as he pleases.
Each victim must satisfy all the Agony assigned to him by choosing from the following options:
- Satisfy one Agony for each of your Units in the Area you choose to Eliminate.
- Satisfy one Agony for each 1 Doom you choose to lose.
- Satisfy one Agony for each Overdue Tome you return to its slot
If the victim does not have enough collective Units, Doom and Overdue Tomes to satisfy the Agony assigned to him, then the remaining Agony can be ignored.
When a player replaces an Overdue Tome to satisfy his Agony, and a Faction currently Controls the Gate in that Tome’s Area, the player Controlling that Gate immediately takes possession of the Tome.
As with the Custodian, no player may take Control of an Abandoned Gate in an Area inhabited by the Librarian. If the Librarian is sent to an Area with a Controlled Gate, the Gate may remain Controlled (for the time being). If you Create a Gate in an Area with the Librarian, it must remain Abandoned until the Librarian leaves.
Additionally, players cannot Battle the Librarian. It is immune to all Spellbooks, abilities, and other effects. The only interaction it has with players is when it is Activated by a player using a Silence Token. It does not have a Unit type.
The only way a player can return a Library Tome back to the Map is by Satisfying Agony as inflicted by the Librarian. You cannot otherwise voluntarily replace it, nor are you ever forced to do so (if you always choose to lose Doom or Units instead).
It is the start of the Action Phase, and two Tomes are Overdue. Cthulhu has one of the Overdue Tomes, and Black Goat has the other. The Librarian is currently at The Oubliette.
Sleeper pays a Silence token but does not Move the Librarian. The Librarian remains at The Oubliette, where Cthulhu has 4 Units. Sleeper rolls a 3 on the Agony die, but since the Librarian did not Move, the result is actually a 4. Cthulhu decides to return his Tome and lose 1 Unit and 2 Doom, satisfying all 4 Agony.
