If it wasn't for Eragon's elvish sight he wouldn't have been able to see his hand 2 feet away from his face. The room he was thrown into was a small box of darkness. With the free time he had Eragon decided to train his mind and expand it as far as he could. He could sense the entirety of Carvahall with little effort. He realized that he sensed Roran in a room laying, frail, and obviously near death, though he could not pinpoint the exact room he was in. Eragon assumed a massive amount of magic was the cause. The magic used was to enable magicians to notice Roran's presence at all, but due to Eragon's enormous magic capability he was able to see and sense Roran, but not the room he was presently in. Eragon knew if he tried he could pinpoint the exact room but decided to let things go the way they were.
"So you're a relative of my grandfather's?" A feminine but powerful voice spoke between into the darkness.
"If your grandfather holds the name of king to this land, then yes I am." Eragon responded.
"If you are who you say you would never have let me sneak up on you." Her voice held a tinge of cockiness.
Eragon could only smirk, "It's cute you think you could sneak up on anyone. You're horrible at hiding your presence. I didn't even need my magic to notice you walking up down hear."
Insulted, the lady tried to expand her mind and intrude on Eragon's, searching for his past and secrets. Eragon immediately pushed her mind attack way and entered hers.
"When you attempt to intrude on other's minds without permission you must be prepared for an attack on yours as well. With this knowledge one must always know how to attack and defend at the same time. Always aware of the weaknesses of their own powers."
She jumped back in horror and began to convulse, her body wanting to pass out, but Eragon reviving her consciousness before she could. Finally Eragon stopped, and she dropped to the floor breathing heavy with a hand on her chest.
"I hate when people intrude in other's minds without permission. Learning every secret about them. Everything they hold dear. I don't ever want you to do that again, Isabella."
"How….do you know my name" she said coughing on the floor.
"Search my mind and find the answer to your question."
He allowed her entry into his mind. Only the parts that she needed to see. That he and Roran were very close, his already known accomplishments: how he defeated Galbatorix, his adventures into Du Weldenvarden and training, and ultimate departure. He left out a lot of the details that would compromise his promises to the eldunarí and himself. He couldn't yet trust her with such knowledge yet.
After her search into his mind she became very humble.
Still putting on her cocky demeanor she said, "Humph, how do I not know you aren't just showing me false images. Your knowledge of magic proves you can do this with ease."
Annoyed by the girl's insolence and stubbornness, Eragon teleported himself out of the cage and in front of the Isabella. She jumped back in shock. Something that could not be done has now been done right before her eyes.
"How did you…"
"It's a technique I've acquired from years of rigorous training. I am the only being in the world who has achieved this magical ability. Now can you show me where your grandfather lays?"
She began to step back in fear understanding the danger the how dangerous the man in front of her was. Suddenly a light began to shine down on them both.
"Oh, what have you done, Izzy?" called a frail voice form above.
"I'm sorry grandmother." Isabella replied.
"Katrina, how nice it is to see your brilliant face after so many years." Eragon said joyfully.
"Oh you flatter. I know of my age. I am no longer the radiant beauty you remember, brother."
"Beauty is more than wants on the outside. There is no other beauty like yours Katrina."
Eragon greeted her with a hug.
"I'm glad you made it here safe, and so fast too!" Katrina had used one of the mirrors given to her by Arya, the queen of the elves, to communicate with Eragon in times of emergency. She had asked Eragon to come to Carvahall and see Roran before he left this world. She knew Eragon would want to see him one last time.
"You knew I would arrive as soon as I could" I am glad for your invitation.
Isabella stood in shock. This young elf talking to her grandmother in such and informal tone. As if they were old acquaintances. "Hellooooo, I hope you haven't forgotten me grandmother. Please tell this trouble doer to leave our house at once!"
Katrina laughed harder than she meant to. "Oh so young and ignorant. They believe to know what makes the sun rise every morn, but in reality don't even know what causes their shadows." Eragon laughed agreeing with her proclamation. "Honey, this is Eragon Shadeslayer. The hero from half a century ago who killed the mad king of a hundred years, a close family relative."
"The pleasure is all mine," said Eragon bowing in Isabella's direction in jest.
She scoffed and turned her head. Katrina and Eragon shared a few more giggles until they left to see Roran. Isabella waited a few moments and left from the darkness herself, using he magic to close and lock to door.
