Lexa + Costia || Goodbye My Lover ||

!AU WARNING! Ice Nation Costia & Lexa arranged marriage AU. I saw a tumblr post where Dany was Lexa’s mum but prefer her as Costia lol. Costia is given to Lexa by the Ice Queen to create an alliance between the warring clans but also to collect information about the Tri Kru. Initally at odds with the seemingly cold and heartless commander they eventually fall in love but when Costia refuses to betray Lexa she is killed.
