Thunderstorm

"We need to get through the barrier and destroy the core." Osvald muttered and looked up.

"The old man said thunderclouds make the barrier unstable from above, but maybe we should go to the Hunters. We'll kill them, and the barrier will disappear." Wain suggested.

"No, I don't think we can do that. If I were them, I'd put the Core of the barrier on the inside, not the outside."

"So we have to go upstairs? Those clouds look formidable."

The clouds near the massive tree continually rumbled with thunderclaps, and vibrations went through the barrier, it quickly recovered, but the top was half-ruined.

"We can get to the top by jumping on the branches. Shall we begin?"

The tree's branches extended outward, making it easy to get to the top. The barrier narrowed toward the top, and the branches grew longer.

"No." Osvald shook his head, "Wain, you forgot something. We have to save the girls. I promised that to Irma."
