The Ylvisaker-Ambrosius Peace Summit was held on A Day Between Years 0, 9001 AI, at the Fortress of the Hylands. It was the turning point in the relations between Ylvisaker and his forces and the Ambrosius's rebel forces.
It was hosted by Jen of the Hylands with observers Dan'l the Wang, the Karland of Kilian, and Duke Dykstra. On the Ylvisaker side of the table was Ylvisaker and Annie, while Ambrosius and Zierath were on the other side of the table.
Ambrosius and Zierath brought in many witnesses and victims of the oppressive laws put in place by Ylvisaker's military advisors, in particular Adam Reisner. Ylvisaker finally reconnected with the mortals and went into action correcting the bad laws.
