Man. If Varian will survive Broken Shore do you really think he will keep his blades? I mean if blizzard wanna pull we found stranger who in reality is "dead" king then Varian shouldn't wear Shalamayne. Because, you know, people will spoil this "great" story line when will see swords.
And yea if blizzard make movie bloodline Lothar - Varian's mother then Lothar - Varrian - Anduin are last arathor line.
