The Princess and the Queen
Alyn Velaryon, formerly known as Alyn of Hull, later known as Oakenfist, was a legitimised bastard from Driftmark of dragonseed descent. His brother was Ser Addam Velaryon, dragonrider and heir to Driftmark.  Alyn was an admiral during the reign of his cousin Daeron I.
After his failed attempt to tame Sheepstealer he carried scars from the dragon's flame on his back legs for the rest of his life.
The Dance of the Dragons
During the civil war, when it was decided by Prince Jacaerys that the Blacks needed more dragonriders, many men on Dragonstone came forward to answer the Prince’s call. Along with his brother Addam, Alyn of Hull was one of them.
Alyn tried to tame Sheepstealer, entering his lair. The dragon set fire to his cloak. His brother Addam used his own cloak to beat out the flames while his dragon Seasmoke drove off Sheepstealer. Alyn counted himself himself fortunate to have lived as other seeds and seekers who aspired to ride that dragon ended being eaten by him instead.
With the Two Betrayers on their minds, many voices in the black council questioned his brother Ser Addam’s loyalty. Only Lord Corlys spoke in defense of the dragonseed remarking that Ser Addam and his brother Alyn were “true heirs” and worthy of Driftmark.
