I have just unlock the Rank of chief serpent Sargent in my GC. But the problem is that I clicked though the text after that said what had opened up for me without reading it. ( I was half asleep.)

So my question is what is now available for me to do? Is it just more GC Leve? Because I once read about something called Hamlet defence and caravan security but I can not find anymore information about them.

Any help I can get would be appreciate.
