Well, since it looks like I'll have the time to do a character for this, I guess that I should ask which of the ideas I came up with should work better. I have one concept for the main team and one for the antagonists:

The first is an ex-saboteur/assassin that lost their purpose in life after the war ended. This one would likely be a younger member of an saboteur clan that didn't even had the chance to join the war before it ended, raised as a human-weapon but with no battle fight anymore, she would be either a vagabond or brigand by the time Chiyuri meets her. Possibly a "Robin Hood" type of character.

The second is a Princess from a small foreign nation that has been subjugated and effectively dissolved by the Empire in the past. I have two ideas that could work with this, one more based on Romania and another being more Eastern in aesthetic (my favorite between the two, if it can fit the setting). Regardless of the nature of the nation, said Princess would be working with Tinnec as an effort to try to rebuild her nation even though she's aware that's a nigh impossible task. Likely, she wouldn't hold any particular prejudice against the main party once they meet, being more of a tragic antagonist than an outright villain. At least the Oriental inspired version, the Romanian inspired one would be more shady, but not really villainous as well.

Either way, which of these would work better for the purposes of the RP?
