You couldn't possibly have missed the point more than you did.
You are Silat the Tribguy.
I am Joe Hero Shaman. In town a nightgaunt comes and takes me away under your watch.
You type who and see there is only one conjurer in range of Joe. His name is Mike the Evil Conjurer. Convenient, no?
So you drop the flag on Mike the Evil Conjurer, because he was the only one who could have done it.
Except you are stupid and are using your player knowledge to know things that your character would not.
Turns out Destanin the Evil Conjurer Guildmaster sent a nightgaunt for me because I had cursed him out only a few moments ago.
So Mike the Evil Conjurer got a false flag because you're a stupid power gamer who plays this game like Call of Duty instead of being immersed in an actual world.
