I've been reading a lot of fanfiction recently, starting with HPMoR then going recursively through Eliezer's 'favorites' list, eventually branching to various TVTropes recommended lists. It's in the latter that I found Destiny is a Hazy thing, a Naruto AU fanfic with major Lovecraftian themes and (currently, at least) minor crossover/shout out elements to Evangelion. The author page has a rather good description. Personally I like this story because it combines a lot of elements I seem to enjoy in fiction, mainly a 'large world' feel and Anehgb univat Lbt Fbgubgu nf n sngure svther (minor spoiler).

I'm currently reading another story by Calanor, Harry Potter and the Puppet of Time

Draco receives the memories of his future self and undertakes an effort to free Harry from Dumbledore's plan without turning him into another Dark Lord and make a better life for himself in the process. Naturally, things stray from their planned path very fast.

Seems to be worth reading as well.

If someone is interested, I can probably spare the time to go over the fics I've read and recommend what I liked, but right now I'll limit myself to Calanor due to his works being sufficiently obscure as to not be easily noticeable otherwise (and maybe other obscure but good authors I find).
