Hell’s Belles – Twitter stream for upcoming Planescape streamed game
Planewalker – My old stomping grounds and still an active community of Planescape fans on their forums.
Planescape.com – Planescape: Torment Enhanced Edition video game for Windows, Mac, Linux, iOs, and Android.
Mimir.Net – Jon Winter’s venerable Planescape fan site. It hasn’t been updated in ages, but is a remarkably creative resource.
Timaresh, The Mirrored Library – A wiki kept for various games in the Planescape setting. While this wiki does include a good deal of expansion and elaboration on existing sources, at its foundation it is based on canon Planescape sources and real-life cultural details, and thus should be usable for any Planescape campaign.
On the Wings of Mephits Planescape Fiction Archive – Another classic that hasn’t been updated in years, but still houses plenty of interesting fan fiction. (Currently hosted by our friends at Planewalker.com)
Other Planar Products and Sites
City of Seven Seraphs – Not Planescape, but a recent Kickstarted project for Pathfinder RPG that is distinctly planar and is being written by a host of amazing writers and published by Lost Spheres Publishing.
Sig: Manual of the Primes – Flavor heavy book about a multiversal city. Mechanics are for their own system, but is very rules-lite and useful for any RPG. By Genesis of Legend Publishing
Paizo’s Pathfinder RPG has the Great Beyond as their planar cosmology. A few years back they published: The Great Beyond: A Guide to the Multiverse and in June 2018 will be their Planar Adventures hardcover. All of it is quite useful and inspiring for Planescape campaigns!
Also, some short Player Companion products from Paizo:
- Blood of Fiends for tieflings
- Blood of Angels for aasimars
- Blood of the Elements for elemental planetouched
And more to come as I find them, as well as one publisher is working on a planar series that I am writing introductions for, but I don’t think they have announced them yet. I will definitely include them once they do.
