The river of time.
The glimpses it shows to some of its chosen travelers get blurred in their memories as mirages. The anomalies don't last long. Sooner or later, the clock resets and everything returns to normal.
Only time can tell what it has in store for its travelers.

The Oni festival was about to start in a few days.
Sharog's private chamber. Durbag tribe. 6 PM.
"My lord, you are back."
Sharog greeted Eren by hugging him firmly. The latter smiles and hugs her back before proceeding to caress her cape-covered back.
"How is everything?"
Eren pulled away from Sharog and smiled. He looked around and found the place to be just as it was the last time he had visited it. He walked towards Sharog's comfy bed and laid peacefully on his back.
The fresh air was making its rounds into the chamber, thanks to the large windows of the chamber. The setting sun had painted the sky golden orange, making the chamber well lit yet not too warm on the eyes.
