Epic romantic fantasy adventure, seriously AU, with angst and fluff in equal measure. I can sense your hesitation, but just give the first chapter a try. It's been winning some folks over and it may surprise you.
There's a reason this is one of the top most popular and most beloved Klaine fanfictions of all time. Chazzam's work is of J.K. Rowling and J.R.R. Tolkein quality, creating an entire universe of custom, history, and language. Whether you're a Kurt and Blaine fan or not, readers will surely fall in love with this world and these characters and this complex love story. It's a far cry from their canon lives, closer to an epic Hobbit/LOTR-esque adventure, but with the added element of finding and falling into true love. Plus, the sex is delicious and beautiful.
Interlude Press is publishing the story as a trilogy, The Heart of All Worlds, and the first part, The Sidhe, is coming out in a few months. I strongly recommend you purchase it, or better yet, look up the original on fanfiction.net, and bask in all its glory.
There's a reason this is one of the top most popular and most beloved Klaine fanfictions of all time. Epic, pure genius, pure magic. A true masterpiece.
