|Died||In 129 ᴀᴄ, at Dragonstone|
|Book(s)||The Princess and the Queen (mentioned)|
Silver Denys was a man living on Dragonstone at the outset of the Dance of the Dragons, who claimed to be the bastard son of King Maegor I Targaryen. His hair and eye color lent credence to his claim.
While none denied that Silver Denys had Targaryen blood, it is not clear if he was actually a bastard son of Maegor, given that Maegor died eighty-one years before the Dance (though Denys's age at the time has not been specified, he did already have sons of his own; no grandsons were mentioned). Maegor was also infamously unable to produce a living heir, despite marrying multiple fertile women. It is possible that Silver Denys was fathered by a different Valyrian.
When Prince Jacaerys Velaryon called for dragonriders, Denys had his arm ripped off in his attempt to mount Sheepstealer. While his sons were trying to staunch the wound, the Cannibal descended on them and devoured Denys along with his sons.
