The Mockery is the lord of treachery and terror. The Devourer commands the destructive powers of nature. The Keeper will strike you down with disease and then snatch your soul so he can continue to torment you for eternity. Everything that we fear—poverty, disease, betrayal, madness, monsters—all of these fall under the sway of the Dark Six. What could drive people to worship these malevolent deities? What sort of player characters would follow them?
In the days ahead I’ll be delving into each of the Dark Six and their followers, starting here with an overview of the Six and a deeper look at the Keeper. Bear in mind that this is my personal take on the Dark Six and the Sovereign Host. It’s not canon material, and it may contradict canon sources.
What do you think of how Keith Baker uses The Keeper in his own games? Does it match how you have been using The Keeper or have you been doing things differently?
Are any of Keith's ideas things that you are going to implement in your own campaign?
