"Well done," he told him. "I guess I'll go first, then."
Ky-Vin walked over and bent down to look through. Definitely open space on the other side, but he couldn't see more than darkness.
He looked at the edges of the hole. They were still kind of hot from the blade of his lightsaber.
The Jedi waited a few minutes, and Ky-Vin saw that the rock had cooled off a bit.
He touched the inside with his hand, and pulled it back. "It's still rather hot, but I think we could tolerate it."
With that, Ky-Vin got down on his stomach and crawled into the tunnel.
There wasn't much space to crawl, but he slowly worked his way through.
After a few moments, he was on the other side. It was very dark, and he ingited his lightsaber to see they were still in a passage of sorts. Up ahead, it turned sharply to the right.
He bent down and called Kenshin. "It's fine, come on through."
