An hypothetical version of the Imperial Conclave follows. . . .
Imperial Conclave [Unique]
In the days of the Empire, the members of the Imperial Temple gathered in the labyrinthine halls of the Imperial Conclave:—a sprawling and ancient structure covering the highest portion of one of the largest islands of the City of Anuire. It was from here that the Pontiff of Anuire ruled, advised by his Cardinals.
DDC: 20.
Build Cost: 100 GB.
Upkeep: 3 GB/turn.
Benefits: This structure functions as a royal palace and a magnificent court.
Once per year the owner may bestow the blessings of the pontificate, thereby granting the recipient domain a +2 bonus to all domain actions for one turn.
The owner may host a grand conclave or a conclave special session each turn as a court action (subtracting 1 GB from the standard cost). The court action enables the owner to host the pontiff's own faction, and an additional court action is required to host each additional faction. Furthermore, any member temple that has an embassy in the same province may take diplomacy as a court action each turn (instead of each year), although the seasonal upkeep for such conclave embassies is 0.5 GB (instead of 0.25 GB).
Restrictions: It is not possible for the owner of the imperial conclave to employ the yearly diplomacy-via-court-action (as per the magnificent court) AND to host a grand conclave or a conclave special session, in the same season.
Also, in a given year, only one diplomacy action (from a given temple's conclave embassy) may be conducted outside the context of a grand conclave or a conclave special session.
Note: The upkeep for the imperial conclave does not cover the upkeep for the conclave embassy (if any) controlled by the pontiff's member temple.
