36. The Rock of Kuthian

Chapter 36: The Rock of Kuthian

A roar sounded in the distance as Sonic flew back from wherever he had been and looked down to see Tails roaring loudly, hoping to catch his attention. The dragon also saw a large red gem beside Tails and wondered what that was. He angled his wings and landed on the ground, looking at his friend.

Hey Tails, Sonic said. Sorry about earlier; I was just really upset about Knuckles' death. What is that red gem beside you?

Tails grinned. This is Knuckles! He's become an Eldunari!

Sonic's eyes widened. WHAT? That...amazing! He looked at the Eldunari. Is that really you, Knux?

The Eldunari glowed. Sure is, Sonic! I transformed into this after Galbatorix killed me.

Great! Sonic said. Well, it's great to see you..."alive." Why did you decide to become an Eldunari?

I just wanted to continue helping you guys, the voice of Knuckles said. Besides, being an Eldunari is pretty cool; I feel really powerful and I'm immortal in this form.

Sonic grinned. Dragons are immortal too, he said. Hey, before we leave, I want to check out the Vault of Souls. Can we do that?

Sure, the Eldunari said.

Sonic walked back to Eragon and Saphira. He smiled and nodded. The Rider and the dragon looked at him curiously.

"What is it?" Eragon asked.

I know that Knuckles is an Eldunari now; Tails told me. Also before we leave, I wanted to visit the Vault of Souls. What Oromis told me about it sounds intriguing and I have to know what is in there.

"I too am curious about the Vault of Souls," Eragon told him. "We will go there. By the way, where did you go when you flew off?"

Oh, I just flew around the island. I found a mountain that had a passageway in it; I am guessing that is the way to the Rock of Kuthian. By the way, I found out what my true name is also.

Eragon's eyes widened. "What is it?"

Sonic told him. The name had such meaning to it and fit Sonic's personality well. Eragon nodded, telling the dragon his also.

That is a good name, Sonic said.

The Dragon Rider smiled and got on Saphira. "We should head over there now," he said.

A few minutes later, Tails walked over, followed by Knuckles' Eldunari. The gem's glow faded as the Eldunari stopped floating, and Eragon put it in his knapsack so that it couldn't get lost or stolen. Sonic roared and spread his wings, flying into the air. Tails and Saphira flew by him also. A few miles later, they saw the mountain that Sonic had talked about. The three dragons landed and saw the passageway.

Is this the entrance? Tails asked.

I believe so, Sonic said.

They started walking down the passage until they saw a massive doorway, and knew that this was the Rock of Kuthian.

How do we open it? The orange dragon asked Eragon.

"Oromis told me that we need to speak our true names to the doorway, and it will open," Eragon told him.

Sonic growled and spoke his true name. As soon as he said it, the doorway rumbled and slid open. He walked inside, followed by Tails, Saphira and Eragon. The three dragons and the Rider gasped in shock at what they saw.

The Vault of Souls was filled with dragon eggs and Eldunari.
