Maegor had been five and ten when he had married his half-sister in a Valyrian wedding ceremony led by his mother, Queen Visenya. His bride had been dressed in the fineries of her mother's traditional Valyrian robes though they were a bit big on her three and ten frame.
The two were raised together on Dragonstone by Visenya after Rhaenys death in Dorne. their Father Aegon raised their brother Aenys in King's Landing leaving the two younger siblings to truly only know each other.
Though, even in his youth Maegor was a brutish child, loud and quick to anger, known to lash out in the yard during training should he fumble a step or miss a parry. But, even so, the order from Visenya had been clear: "Watch over your sister."
The daughter of Aegon and Rhaenys was small for her age, just as her eldest brother had been and she was a bit more frail. She spent her youth toddling after Maegor and then following in the Queen's footsteps to learn the ins and outs of ruling the island of Dragonstone.
The young girl often could be found sitting in the shade of the training yard, watching her brother and the Kingsguard train. On the colder days, her weaknesses kept her inside the castle, but watching through the window.
Maegor took his duties more seriously than any other child his age and that hardened him into the stoic man he was today, always keeping a watchful eye on his sister-wife. Now ten years into his marriage, he was still without an heir to show for it.
There was one place Maegor could not bring himself to go, no amount of training or battle could prepare him for the birthing chamber where his sister-wife now fought. Their third pregnancy toiled on behind the cracked door where he stood gripping his belt to hide his trembling hands.
"The babe will not turn, my Prince, there is little more we can do," the Maester said as the sounds of her labor echoed in the corridor. Maegor was frozen in place, his mind raging: watch over her...
"Let me see her," Maegor finally spoke after a shrill cry of yours.
