The Ferdiad Cycle
After the hordes of the Chimeira ravaged the northern provinces in 949 a bill called the Oatheep Pact was made to make sure another large scale invasion won’ take them by surprise. It dictates that the northern provinces must allocate a certain amount of troops at all times to secure the borders along the planes of Ysgrid and to have the farther reaches of them scouted regularly. As this is paid mostly by the northern rulers themselves the pact has caused great displeasure amongst them leading to the rebellion by Lorr magh Cewren who sought to separate the province of Ffroth from the rest of Aenoria. His plans were quickly put to an end by the combined forces of other Thanes who executed the renegade for oathbreaking in 995.
