Wizards of the Coast is pulling out the stops for it's new Rage of the Demons campaign and I have to admit I am rather excited about it myself.
There is a lot going on here. Including the new Out of Abyss book and Rage of the Demons minis.
Though how is any of this going to affect the Order of the Platinum Dragon? Simple. This is a multiversal event. While all that stuff is going on in the Realms and the Sword Coast, over here in my world we are still running through what I call the "Great Greyhawk Campaign" in my campaign of the Endless Darkness.
The two campaigns are obviously linked. I'll adapt bits and pieces from the Rage of Demons to put into my campaign.
I am excited to see Demogorgon in this and the mindflayers. Mindflayers working with Orcus, that is like custom made for my games.
