Felix Martialis

Felix Martialis was an elderly Roman man, who managed Krokodilopolis' arena in 48 BC. He initially sent Bayek away, but was then persuaded by Kensa to let Bayek fight the Gallic brothers Diovicos and Viridovix. After Bayek's victory, Felix told him he should also attend the arena of Cyrene.
