Can you solve this League of Legends riddle about Riven?

Yup, so after a few minutes of tinkering i'd solved the first bit, but after opening the document, i get insta-migrained. I simply dont understand what the F1, B[]N, C1 yadda yadda symbols mean.

Here's the opened word document:

I'm currently analyzing riven's story to find similarities with dante here. But without understanding the F1/C1 things i'll never get anywhere. So i was hoping that some intelligent people might be able to explain or maybe decode the paragraph.

Also, the final answer is probably only one word. For example, the last new free champ's(talon) code boiled down to Hashishin, which is japanese for assasin

Anyways, in case you guys were wondering why im doing this, in garena lol, there's 5 winners for every new champion, in this case you get riven for free. Thanks guys if you'd help. though there really is no reason to >.>

Man i really wish i took cryptology
