Actually, Trillian IS a Steiner-Davion. It's why she was sent to the FedSuns as an ambassador.
With that aside, I do not expect to see Trillian handing over the throne to Alaric just because of his claim. It IS interesting b/c it puts the Clans involved in a potential dynastic squabble.
Ok. Trillian is a Steiner-Davion, like Alaric, although I'll still suggest that most Lyrans consider Steiner-Davion the cadet branch, any more. Even still, Trillian's claim is legit, Alaric's is not, but does the Republic give less than two-tenths of a half of a crap about it? Magic 8-ball says no. Or Maybe. Or yes. Depends on how many times you ask, maybe.
About expecting the Lyran Succession to be settled by ANY Clan, one with the blood of a Steiner-Davion or not, especially KATHERINE, lol. I mean, I'm not here to pick a fight with Clan Wolf, if your getting that impression, but, Alaric-fans, how delusional do you have to be to even entertain the thought that any authority over any Lyran world can descend from Katherine.
Alaric can play the scourge, he may even take Terra and replace the RotS regime with one of his own.
He will never be Archon. General war would ensue, I tend to think, and would not end until he was dead and Clan Wolf had a new Khan with a mandate to keep his hands off of the LC.
This is all just idle speculation, though. We'll see what the new Line Devs will reveal.
I hope it happens before I'm over Steiner and on to something else, but, you know, don't give up the ship.
