The Maar Sul Ball was a lavish ball held by King Gerard Aurelac in Maar Sul City in the spring of 1017 AE to celebrate the Grand Alliance's arrival to the city and the resulting signing of a treaty of goodwill between the kingdoms of Remon and Maar Sul. The ball was interrupted briefly by a surprise attack from the Nightstalkers who kidnapped one of the guests, Tiyana Natiya, before fleeing albeit some of the Nightstalkers were caught afterwards. As a result of the ball, the Grand Alliance would begin planning the invasion of the Proninist-occupied Jardine with Maar Sulais backing and later led a campaign to the Sultanate of Karaganda.
