This is a really cool idea, I hope there is more planned for Baxtorian
I would love to see the Tarddian afterlife either way... although I'd rather have more of Tarddiad first. There must be some ruins of an "Old Prifddinas" somewhere, right?
I'm sure he's got something up his sleeve, though that doesn't make me think he'll go ham on everyone just while he's surrounded by Seren with a whole army of elves ready to belt anyone who's daring to disturb their homeland's peace.
All of his plans would have to be discussed with a tier 2 goddess- that is his moves should be subtle and very calculated- whatever he's trying to achieve should (indirectly) make Prifddinas's elves (seem) more secure.
Him being on Seren's side might make his actions seem more legitimate to the elven population, though whatever he does would have to remain within the elven race's own interest. Either way, I wouldn't be surprised if he's already bargained with some of the clans in Priff and if he's discussed the future of the elven race beyond their confined space.
Remember this guy had been a ruler for centuries, having mastered kingdom management he knows how to take on responsibilities. He's got this holistic chessboard kind of view over his subjects, his enemies and whatever goal he has in mind, so in short politics is this guy's expertise; he could well F@#% stuff up if he really wanted to in a machiavellian kinda way.
One thing I could imagine him doing is trying to reach out to neighboring kingdoms to either extend his own sphere of influence in a diplomatic manner, merely showing off his muscles, urging to get hold of some vassal state, saying:
"Hey, remember my name? Time to respect us or suffer the consequences"
; OR in the worst case, he'd regain some sort of settlement through military means, in order to secure the area around his beloved tomb.
For example, he could avenge his brothers and sisters by "cleansing" the lands from human invaders, avenging fallen elves in a massive bloodbath to re-establishish balance between gnomish, human and of course elven spheres of influence. This would give Seren's circle carte blanche to gain leverage over whatever part of terrestrial Gielinor, including gods.
Sometimes one must operate within the
shadows
to serve the
light
. For a man makes no noise over a good deed, but passes on to another as a vine to bear fruits again in season, in order that the world may ever be new.
