Also one thing to mention, Jinshi was young by the looks of it when being granted the Magistrate title, so the war being about a decade ago seems to be correct as Jinshi now is a lot more older. (Edit: Damn that was wrong by a long shot huh, a lot of it)

0:51 I think what is rare is the Sentinel Jue directly assigning the role of magistrate (hand picking)

Also Jue Dragon curled position the symbol of Infinity . And also Jue is a New Boss in the Next version as per the dev release.
