Dottore and you were great enemies...but after the war against Celestia...Teyviat was restarted and only those who had the most impact on the war have their memories

Dottore now calls himself Zandick again and lives in Sumeru again, being disowned...Dottore/Zandick is someone physically weak and can do little to defend himself

But now a surprise would hit him while he was in class
