Imyrr Rousseau was the fourteenth modern bearer of the fabled Staff of Nicator, having won the Year 902 championship games.
In the year 922 AF he adopted the regnal name Invictus in honour of becoming the first Emperor since the fall of Seleucar. References to Imyrr Rousseau predate this crowning, while references to Invictus postdate it. Both refer to the same individual.
