It couldn't have been more than 10 minutes in which he crossed over half of the plains of Unworthy death. He could have went over to the beacon tower of he wanted.
However, this thought did not cross his mind as he dashed through everything to his destination without rest.
Finally he stopped. Esdras looked around, this was the northwest of the Rite grounds and right by the plateau cliff, there was nothing behind it but rocky mountains. This was the end of the plains of the Unworthy death.
Yet, he didn't see Celine. This is where her tracking stone was last before she disappeared. Roughly. And yet there was nothing here. Not even a trace of a battle or anything of the sort.
Esdras suspected that the tracking stone just broke in the middle of a heated battle or maybe Celine lost it by mistake. She was after all, clumsy at times.
Celine knew how important the stone was and wouldn't discard it by intentionally.
