It was whispered amongst Dragonstone that there was a third sister to Aegon I and his sister-wives, but no one had ever saw her. It was a rumor to most, especially after Aegon, Visenya, and Rhaenys conquered the seven kingdoms. Maids and servants spoke of possibly seeing her but no one higher could ever confirm it so they just believed it was the maids gossiping.

One of the terrible things about it was that Aegon wasn't even sure if it was true or not. He only ever remembers Visenya and Rhaenys. The one he'd be forced to marry (he really did love her, but as a sister), and Rhaenys, the one he had truly wanted. He honestly forgotten about the rumor after he moved to Kings'Landing and stopped coming back. He remained clueless until after Rhaenys died.

In order to get away from everything, he had returned to Dragonstone alone, leaving Visenya to rule alone after she had insisted that she could and of course, he trusted her.

So, upon returning to Dragonstone, he realized that those rumors that had been going around since he was a child still exist. He wanted to try and figure out what it was... so he started sending a servant that he trusted to ask questions and those questions slowly but surely led him to the dungeons, he had never been in here... he realized.

A sick feeling was in his stomach, if it was true... Oh god, he might actually throw up. One of the oldest men that had worked and lived in the castle since before he was born whispered about his father, whom had not been the best man. He didn't know what he was getting into at this point as he walked to the deepest parts of the dungeons where he knew a select people went but he hadn't ever wondered why... not until now.

Aegon continued looking before he stopped at the end of the hallway, there was someone on the ground.... curled up. She looked small and rough, very rough. Nothing about you was clean or healthy. "Hello?" He asked, trying to be quiet as not to startle you completely but he wanted to make sure that you did hear him.
