As with many records of the war, Nicoli Merseneos den Ballin's detailed history is not known. What is known is that circa FY 1090, a noblewoman named Esmara Getare overran and conquered much of what is now Illian and the Plains of Maredo before launching an assault on Andor. This assault was defeated and Getare was taken prisoner by Queen Telaisien.
Following this event, Nicoli Merseneos den Ballin's army captured Illian. It is uncertain when, although his name suggests he was a native of the city of Illian or the surrounding area. Nicoli proclaimed himself King after taking Illian, and won the support of the people and the nobility for his rule.
According to records, Nicoli Merseneos den Ballin was considered a "fair and just" ruler, noted for his wisdom in creating the bodies known as the Council of Nine and the Assemblage to help him rule over the kingdom.
Nicoli Merseneos den Ballin ordered the construction of the King's Palace early in his reign and granted permission for the Council of Nine to build a "Great Hall of the Council" on the condition it was not as large as his palace. He was unimpressed to discover their hall was in fact an exact copy of his palace, merely two feet smaller in every dimension.
It is unknown how long den Ballin ruled for, or when he died, save that his children succeeded him as the ruler of Illian, and his family retained control of the kingdom for over three centuries.
