Their name may be unfamiliar as the line has died out by the timeframe ofGame of Thrones.
While no information is given about lord and lady Cargyll, they obviously have cruel senses of humor.
Why else would they give their identical twin sons virtually the same name?
In addition to having almost the same name and face, the brothers have the same job.
They serve in Viserys' (Paddy Considine) Kingsguard, making up two of the elite seven.
But when the royal house divides, serving them becomes more difficult.

First, they go to a place where poor children are forced to fight for entertainment.
There they see a small boy Erryk says is Aegon’s bastard.
Erryk is disillusioned with the prince’s behavior.
He wants no part of a kingdom ruled by a man like Aegon.
But Erryk remains unconvinced.
With the help of theWhite Worm, the brothers find Aegon.
Arryk fights Cole, but Erryk decides not to help.
On the other hand, Arryk seemingly desires to support Aegon.
Erryk is in Dragonstone protecting Rhaenyra when Viserys dies, while Arryk is in Kings Landing with the Greens.
In this case, they each side with the people they are with at the time of the division.
It’s more convenient to support the people around them than let them imprison them.
The show also has the added complication of Errrk needing to escape Kings Landing and find Rhaenyra.
But this simple change gives the character volition and shows the position so much of the court is in.
Arryk picks his duty, but his brother chooses to do what he thinks is right.
This contrast highlights a conflict prominent inGame of Thronesthat now makes its way intoHouse of the Dragon.
Showing Arryk and Erryk debate which side to support shines a light on the issues at stake.
In the hallways of Dragonstone’s citadel the brothers fought to the death.
But another story is told byone ofFire & Blood’s contributing sources.
The tragedy of Arryk and Erryk shows how divisive the Dance with Dragons is.
The war leads to the demise of the dragons and, eventually, the Targaryens.
These brothers are so close at the beginning, and they fall out over this war.
