The Moks Handshake/Language
So you have the Moks Tribe, and their brief official Blurb here.
A tribe invisible for the fact that its members are spread out across many different tribes (unbeknownst to those tribes). Communication between its members is done on the rare occasion when two tribes meet, through an ancient set of hand signals only recognizable by those who know what they are looking for.
Which just rereading that again...I think I have completely missed what they were saying in actuality with it. I had always read that paragraph and assumed by secret hand signals. That they meant that was how Moks signalled to each other to let each other know "Hey its cool I'm a Moks too." You know essentially a secret handshake that only they knew.
But holy crap I'm a moron and didn't realize that's not what they mean at all. Because the sentence is set up explaining HOW communication is done not how they know each other.
Basically the Moks may have a special handshake, but the Moks actually have their own entire Sign Language they use to communicate with each other in secret. Thats why no other Tribes have hard evidence on the Moks beyond "Yeah we think they're around." Since think about it, even if you had a special handshake you did before you spoke to one another. Someone else can come into earshot and hear you speaking about things completely unrelated to the Tribe you are currently living in. This would raise suspicion and cause people to investigate to find out what is really going on. This would quickly result in members of the Moks Tribe being discovered and outed.
But if your ENTIRE communication with your Moks Tribe is through Hand Signals and body language, then there is nothing to be overheard you can speak however you want and your surrogate tribe will never know the difference. Plus even if someone walked in on you while you were speaking to a Moks with this sign language, you could very easily and smoothly brush it off. Not to mention you could have your bodies positioned so anyone that walks in won't see your signing and whoever see them enter can quickly sign to you to 'Act Natural'
It just makes so much more sense on how they'd stay invisible with a sign language that is unique to them. Because to anyone else it'd just look like some silly hand gestures or potentially just odd idle movements. Anything except a deliberate communication attempt unless they were being extremely blatant about it which they're probably raised not to be.
