Would you be okay with it if they had canon versions? If so, could Terrah's canon counterpart be the father of Lavitka Horton? And could Andrea be a very distant descendant of a Valkyrie born in -72?
Alright then, sure! Go ahead (: Sounds interesting. Wait, who's Lavitka again? I remember a Lavitka Neumann from way way back on Vresun but I don't remember a Lavitka Horton.
