Aenor Greenfyre, the hidden child of Prince Duncan Targaryen and Jenny of Oldstones. Nobody except for two nursemaids, a maester, and Benfry Blackwood the younger brother of Betha Blackwood and Prince Duncan's close friend knew of the young Princes' birth. When the events of Summerhall came to light, Benfry, fearing what might happen if Aenor was revealed to be the son of Prince Duncan and hence a contender for the throne regardless of Duncan's abdication; took the young prince to Essos. Eventually Benfry married the daughter of a Magister in Lys who raised Aenor like her own son.
From there Aenor grew up seeing Benfry and Lisana as parental figures. Aenor grew up to inherit most of Duncan's features except for his eyes which was green like his mothers. Aenor soon took over as the new Lord of House Greenfyre, taking the name from his mother's eyes, after the untimely death of his adopted parents.
