So
@SoaringHawk218 , who would be eligible for the Seals that are on the table here?
Kelton, Phoebe, Axton and Lancel would be eligible for the Knight Seal. Elena and Alejandro would be eligible for the Mercenary Seal.
I'm going with FE 8's branching promotion paths, so each character would get the chance to promote into one of two advanced classes. For example, Kelton can either go Sentinel (giving him a more defensive skill) or Champion (giving a more aggressive skill). I haven't decided exactly what those are yet, but when the time comes to promote I'll tell everyone what they are in advance so you can make an informed vote.
I'm also probably going to let you choose which seal or weapon you get rather than rolling it. I was thinking along the lines of players getting assigned something in the games, but in hindsight that feels a little mean.
As for Artemis and Ryza...
And on a related note - Artemis and Ryza's promotions are likely to be progression-locked in some form, like most FE lords.
Quoted for truth. Artemis will get a Heaven's Seal equivalent eventually, which will promote her into her single promotion class. I've already decided on her skill:
Chosen by Fate: Starts with Advantage in all combats, though Advantage can be lost depending on circumstances.
As for Ryza... well, her's will be a sort of pseudo-promotion, and depending on the exact circumstances and votes it might not appear, there's a very specific thing that must happen to do it... but I guarantee, if it does come up, it'll be a
big deal.
EDIT:
It's not going to be some kind of thing that we have to do Horrible Sacrifices to acquire, or effectively blindly walk through just the right series of events sight unseen to unlock though, right?
It certainly isn't a Horrible Sacrifice, and while it does require a specific event to occur, there are many, many ways for that event to happen, and I'll tell you right now I have an active interest in making that event happen, so unless you lot determinedly avoid it, it's likely to happen. I just wanted to say that it's one of those things that's technically missable
I and certain in-universe powers intend for it to happen.
