Then the people of Luria 1000 years from now could have pilgrimages to see all of the chunks of Brom spread across Dwilight (since obviously Luria conquered everyone)
Ooh! Ooh! Luria Vesperi calls the head! I'll put it in my study and use it for holding quills or something.
Not as much as they are overestimating the Lurias.
Fatal mistake right there. Imagine if we weren't all backstabbing and fighting each other - all that shifty malice and militant fury would be directed at the rest of the world.
Here's what I suggest:
Tidy up, make Luria all united and everything then invite Brom to come back. BAM! You've just destroyed your unity.
Namely: The entirety of Luria devolves into Civil war over who gets to hang my character.
Until something like this happens. Luria does seem like the only place to hypothetically civil war over who gets to kill one man.
I guess Hendrick would have to do it? For honorable reasons of familial revenge? He can't even hold a sword...
