Erik Lehnsherr/Charles Xavier
Word Count: 625,982 (unfinished since 2015 but worth the read)
Explicit - Dystopian - Kidnapped - War - Violence - Trauma - Torture - Child abuse - Angst - Hurt/Comfort - Tension - SLOW burn (bruh) - GOD-Tier writing
Snippet Summary: Charles is kidnapped to be used in a war, Erik is the war machine locked away in the mansion, Emma Frost is the leader.
Personal Opinion: CHERIK CLASSIC! Where do I even start? This has ruined me. It is so good. The writing is seriously some of the best ever, like ever. The tension, the character development, the slow burn (please), the side characters, the political plot, everything. is. amazing. This has been unfinished since 2015 but it is worth the read. It ends right as the climax begins but it is WORTH THE READ! You will struggle to find anything as engaging, gripping, high tension, and interesting as this.

Erik Lehnsherr/Charles Xavier
Explicit - Dystopian - Mpreg (similar to ABO but not quite)- Forced Marriage - War - Emotional abuse - Slow burn (?) - Politics
Snippet Summary: Charles accidentally starts a bond with Erik, Erik is determined to follow it through regardless of Charles opinions.
Personal Opinion: I am only including this in my rec list to warn everyone. If you want a happy ending or even a logical ending, do not read this. Erik is annoying and does not develop or change at all, in the worst way. The ending is very disappointing. This had so much going for it, the writing is good, the politics and world building is good, but the romance is just… not good and very disappointing and sad.
