Gunthor Darklyn
Gunthor Darklyn was Lord of Valle Oscuro and head of his house during the years of the Dance of the Dragons, the succession war that split the Targaryen realm in two.
His name is tied to the black faction: he was among the first lords to back Princess Rhaenyra's claim to the Iron Throne.

Gunthor Darklyn led a house that already had a presence at court: his uncle, Ser Steffon Darklyn, served in the Kingsguard. When King Viserys I Targaryen died, Gunthor sided with Princess Rhaenyra against her half-brother's claim.
He joined the group of lords who made up the Black Council, the body that upheld the princess's cause at Dragonstone.

Valle Oscuro was the first place Ser Criston Cole struck when King Aegon II decided to punish the rebel lords. The city was sacked and Gunthor Darklyn was beheaded.
His death, added to that of so many others who fell in those days, led House Darklyn to scale back the support it had given Rhaenyra.
