So what exactly is this "Another Crisis" doujin I keep hearing about? Does anyone know where you can find it in English or something?

Pic unrelated but Vita.

As near as I can tell, as I do not have the doujin in question, "Another Crisis" posits that the only challenge Nanoha could have would be... Nanoha. Not a clone. But rather becuase of the Infinite Earths theory, there is another Nanoha out there who is just as powerul as the canon, but skiped the friendship part, becoming a villian out to destroy everything.

Thanks 4chan's anon. I too searched for a long time for it doujin until they gave me the link

Deliver an attack.
starlight breaker ex + program execution, sonic mode custom universal + short zamber, improved Extended auto mega advanced insulated jacket etc.

Sadly that's in Japanese. No English translation anywhere?

unfortunately not, there hasn't been any signs of an English translation for them.

I have posted translations on the Nanofate forums for chapters 1-2, and info about Raising Heart Destroy and why it's so powerful.
