Ben Plumm

Ben says he is part Braavosi, Summer Islander, Ibbenese, Qohorik, Dornish, Dothraki, and Westeros. He claims to have a drop of Targaryen blood, which must be why dragons, particularly Viserion, have an affinity for him. He states an old member of House Plumm married a "dragon princess". He vaguely says that the wedding took place in the reign of Aegon Targaryen. Daenerys points out that there were five Aegons who reigned in Westeros and asks which one, but Ben fails to remember the regnal number requested. Tyrion Lannister suspects him to be a distant descendant of a younger son of Viserys Plumm and a possible distant relation to the famous Ossifer Plumm, and that Ben thus has "two drops" of dragon blood, not just one, as Viserys Plumm was rumored to have been fathered by King Aegon IV Targaryen on Princess Elaena Targaryen, Ossifer's wife.
