Geoffrey du Temple

Geoffri du Temple or just Geoffrey, was a fifth generation Ventrue, childe of Alexander of Paris.

He deposed his sire in 1222, with the help of a conspiracy of the Courts of Love who involved even the magi Goratrix, of the Tremere.

After the coup Geoffrey became the Prince of the Grand Court. At the present time, however, most of the High Clans in France are too busy squabbling and politically fencing with one another to take full advantage of the wealth of opportunities  the  nation  provides. The Grand Court, a Ventrue-Toreador alliance currently ruled by the Ventrue Prince Geoffrey of Paris, had been swiftly losing the power it has held almost since the fall of Rome.

The young prince enjoys support from a number of powerful Cainites — including the Toreador Salianna, Matriarch of the Parisian Courts of Love and an ally of both Prince Mithras of London and Hardestadt of the Court of the Black Cross — but his relative inexperience at matters of leadership and the many bargains he made during his efforts to overthrow his predecessor now conspire to limit his effectiveness. The individual Courts of Love across France, most of which are  heavily  dominated  by  the  Toreador,  are gaining power, and some have come to rule their local provinces or cities with almost complete autonomy. Geoffrey is  currently  making  efforts  to  regain  his authority,  and  several  of  those  to  whom  he  owed substantial debts have vanished in recent nights; for the  first  time,  Geoffrey’s  name  is  spoken  in  some quarters with a hint of fear, rather than the tinge of condescension which had become commonplace.
