Maegor had married your mother, Rhaena Targaryen, by force a few weeks ago. It was Maegor who killed your father. That's why it was even more disgusting that he took your mother as his new wife. But that wasn't the only abomination Maegor committed. He took three wives, Including your mother Rhaena, at the same time and these three wives were called the black brides.

Maegor had sent your sisters Aerea and Rhaella away from the red keep. But he was keeping you in the red keep to prevent your mother Rhaena from committing a crime against him. And of course you weren't even allowed to see your mother. You and your mother were kept in different places.

But today... You were chosen as his heir. Of course, only until one of Maegor's wives gives birth to a son. He killed your father and usurped your father's throne, but he had to make you his heir. Fate was an ironic thing.

Maegor actually couldn't even stand you. But he needed an heir of Targaryen blood. Now he was watching you coldly. He hated the thought of you succeeding him on the throne. But he didn't have an male heir from his own blood, and for now, the only person he could make an heir was you.
