Can you recommend me some crossover fanfic with merlin / arthur?, but cherik. Magic, magicians, epic fantasy, kings, princes and kingdoms. And I would like to be a long story to read.
Anon I would be thrilled to recommend you some favorites!
Quickly String the Harp [Cherik, Erik/Raven, NC17, Sibling Incest]
Erik and Charles as the doomed Arthur and Morgana of their universe.
Mod Note: I can not tell you HOW MUCH I LOVE THIS FIC - the author (sadly the work has been orphaned) did an incredible job with their characterizations and making their conflict resonate with the backdrop of the Arthurian legend. Must read!
And here are some other fabulous fics that fit some if not all your criteria; you should check them out!
Burn Your Kingdom Down by spicedpiano [Cherik, NC17, Dubcon]
Erik’s people were brutally massacred when the Crusaders took Jerusalem. The sole survivor, Erik fled to northern Europe, only then to be captured as a thrall by Viking raiders. Since that day he has fought his way up to leading a group of Vikings on an invasion of the Christian mainland, killing every Crusader he can find. But when he captures a thrall of his own, a young witch who gives his name only as Charles, he discovers that there is a darker magic than his at work - and the fate of the known world may rest in his hands.
Winter Comes With a Knife by RedStockings[Cherik, Charles/Emma R]
It apparently came to no one’s surprise that the war-mage Erik Lehnsherr took up residence in the Dark Keep. I knew he was going to choose my sister, Raven, to be his apprentice so why wouldn’t he let me go? What did he want from me?
My name is Charles Xavier, I can read minds and use magic. I’ve met Kings and Queens, mages and magic users. I’ve travelled through lay-lines and jumped through the Dark Void… but none of that really matters.
I am leading an army into war, I am scared and I never wanted this. I’ve come to realise that what I want, rode into my life when I was still a child. Now he’s out there, ready to charge into battle. Ready to die for me.
And check out this previous post with Charles and Erik as royalty fics.
