Well, I may not be an expert in fanfiction, lore or writing, but I really liked it! The story was really good, enough to keep me reading because I wanted to, and not because I had to finish it.
+1 for random lesbians moments, because Ahri is way too sexy to not use her for fanservice!
Really cool fights, especially Shyvana's and Jarvan's. And talking about Jarvan, I liked how you made it sound like a little royal ass*hole at the beginning, and suddenly turned him into a hero, sacrificing his life for Lux and risking it just to take Leona to a safe place.
Can't wait for the last chapter, and to see Swain's plan, LeBlanc's favor (if Lux returns, which I think will happen, you just don't take away the main character's best friend/lesbian crush without a proper ending) and Pantheon's reaction. Cuz, I'm pretty sure everyone wants some more Mantheon, maybe him yelling at Leona that all those people had to make those sacrifices just because she wasn't focused and she didn't know her limits.
