Zed’s Order of Shadow was inspired by the Navori Brotherhood (Irelia’s Resistance Group)

So, earlier today I was in a discussion with some people from the Syndra Main Discord about Syndra and somehow the topic drifted to Zed. As an avid SA&S Boards reader I remembered that WAAARGHbobo posted a timeline about Zed. While I reread it I noticed an interesting thing.

[...] Noxus invades —zed witness war crimes. Kusho’s refusal to help the war effort is the last straw, Zed is no longer sympathetic or allied to the kinkou. While not directly opposed to them— he begins to view the kinkou as rivals. Zed forms his own order— related to the Navoi militia group. (Spelling?) Some vastaya tribes looking for a better deal, ally with the Noxus. Others fight for Ionia. Zed begins hostility with non- humans. [...]

Navoi militia group. WAAARGHbobo even mentioned he was unsure if he spelled it right. It was supposed to be Navori. Navori is not a new name for sure. However, there is one mention from a military order in Eduard Santangelo's Vastaya Field Journal.

I’ve experienced the grand misfortune of being kidnapped. My captors – a surly lot who call themselves the Navori Brotherhood – suspect I am a Piltovan spy. Naturally, being a man of the world with varied intellectual, athletic, and romantic skills such as [edited for brevity], I was insulted at the accusation.

Of course, this is only a theory and I could be wrong with it. But I kinda doubt it since WAAARGHbobo does talk pretty often about Zed and it isn't unusal to have hidden hints in other, older lore.
