What happened in those few hours?

"Follow me," The centaur said, finally fully lowering his spear. Having kept it raised a few more seconds after learning about Eldrian's identity. 

Eldrian did not mind his delay and followed as instructed. He decided to not ask questions right away. As clearly this centaur did not wish to talk. 

Entering the inside of the damaged wooden walls of mostly logs, Eldrian was truly shocked by how bad things looked. However, contrasting the last battlefield he had been on, there were no corpses.

More specifically, there were no human, centaur, or demi-human corpses. There was plenty of rotting beasts and piles of bones. The contrast making him all the more curious. 

The only place that was unaffected was the cabin, the centaur having told Eldrian to enter after leaving. Doing as he was told, Eldrian approached, realizing that the door of the cabin was no longer present.
