House Fortezza is an alternate universe campaign based in the world of George R. R. Martin’s Song of Ice and Fire. The campaign focus’ around the Fortezza family and their banner men House Kerieth. Both family’s have holdings in the hills of the Westerland’s and just south of the Tumblestone.
The campaign follows the SIF story arc but takes liberties in events. An example is when player character Jalag Kerieth saved Tyrion from the Eyrie, instead of Bronn. The original campaign was centered around 5 characters but has since been split by circumstance — just like in the real SIF. ( and by real I understand it is a work of fiction. )
