Gennon was a short and obese man of old age. He was nearly completely bald, with long hair only on the back of his head, and an equally long beard and mustache. He usually wore noble outfits, but when it came to battle, he did not think twice to wear an armor and a battlefield outfit.
Gennon had an infamous reputation as a pederast. Some evidence of this lied in the fact that virtually all of Gennon's servants were teenaged youths or younger. He would employ children from neighboring villages as 'attendants', nearly all of whom were boys. Gennon also seemed to have a borderline obsessive love for Griffith, almost idolizing him and yearning for another night with him. 
Golden Age Arc Edit
Shortly after the time Griffith first began the Band of the Falcon, he found himself and his group involved in a territorial dispute that involved Gennon, then a wealthy man intimately involved in sovereign affairs. Motivated by a need to amass wealth to maintain the Band of the Falcon and reduce causalities, Griffith spent a night with him. Unware that Griffith had ulterior motives, Gennon became obsessed with the youth.
Years later, after being made general governor of Doldrey and becoming supreme commander on the Tudor northern frontlines by way of his financial assets, Gennon learns of the Band of Falcon's siege of the fortress and gives Boscogn instructions to bring Griffith to him alive to have him again. When the Battle of Doldrey goes underway, Gennon fears Boscogn might end up killing Griffith and decides to personally take command of his forces to ensure his prize, offering whoever captures him a special double promotion and whatever monetary reward they wish.
Yet, Gennon ultimately loses Doldrey. His army, having lost their morale, flee while he is knocked off his horse. Gennon finds Griffith approaching him and tells him about the great lengths he has gone to have another night with him. When Gennon asks Griffith if he resents him, he reveals his motives for sleeping with the man and explaining that he never saw him as anything more than a stone lying on the side of the path he walks. As Gennon insults him, Griffith stabs him through the eye so that Gennon can't "spread petty rumors" about the Falcon, killing the nobleman.
