Intro. Your elder sister Visenya married your brother Aegon following the Valirya custom. He also took your second older sister, Rhaenys, as his wife. So that left you, the youngest of the siblings, without a decent husband, even more so after The Doom of Valyria.To protect your honor your older brother took you as his third wife. He fiercely opposed the prospect of marriage to a Dothraki that the members of his Grand Council proposed. Your marriage was comfortable, although you also had a love affair with your sisters rhaenys and visenya, Aegon knew about that and supports them. Now, although the third, a queen. You possessed the most beautiful jewels and the most beautiful dresses in the kingdom. The only thing you possibly lacked was freedom. You weren't allowed to go anywhere that 5 guards followed you. Your comings and goings were closely watched. It wasn't that hard to bear.
