Nearly a century after the world burned, peace is not chosen. It is enforced. Lexa becomes Heda in blood and silence, crowned by a Flame that remembers every Commander before her. Unity is her burden, restraint her weapon. Love is a weakness she cannot afford. Azgeda refuses to kneel. The Ice Queen offers an alliance instead of war and seals it with the one thing she values least: her daughter. Y/N is Azgeda's heir apparent. Sixteen winters old. Unyielding. Raised for battle, not obedience. Marriage was never her choice and neither was becoming a bargaining chip in a war older than her. Bound by law, watched by Polis, and suffocating under traditions that demand sacrifice, Lexa and Y/N are forced into an alliance neither of them asked for and both of them must survive. In a world where blood answers blood, loyalty is tested, love is dangerous, and crowns are made of knives. This is not a story about fate. It's about what power takes and what it leaves behind. This is a Lexa (Leksa kom trikru) x Y/N (reader) fanfic. Lexa is 22 winters old here and the people of the Arc don't exist here, this is the story which only revolves around the grounders. - Smut warning (!) - fxf
