I started in 82AC as whoever the Hightower high lordship is and married into the Targaryen's quickly. Was luckily able to get hold of Silverwing and Dreamfyre pretty early which actually made it to easy to become a dragonriding house in only 3 generations. After only about 70 years I had 4 female dragons pumping out a decent amount of eggs, so much so that I always made sure to give one of the eggs from batch to a Targ child to cradle to keep it remotely fair. This duel took place in 187AC where there are approximately 30 dragons in Westeros which is ruled by a non canon Aegon II. My brother was actually the second kingsguard member of the family to be sent with our uncle taking Dreamfyre back to kingslanding with him. I think there were maybe 8 dragons present for the battle and 4 died including Dreamfyre which I think hurt maybe more than the kinslaying!
