He was known as the sleeping dragon. Because he was a man of high intellect and learning, but chose to live as a hermit, not utilizing his ability. Which fits the mc well, since wilfred rates him highly, but he does not utilize his talent due to fear.
And I suspect they'll have a similar rise. Zhuge Liang was convinced by Liu Bei to come out of his hermitage and utilize his talents serving Liu Bei. And I think the mc has his own Liu Bei in Luna and Gracie(though I suspect they won't convince him but that he'll be forced to rise up when they end up in mortal peril).
