Let's start archiving this stuff.
Quickleaf
Fantasy Taken To The Edge (The Power of Belief, Aasimar and Tiefling races)
Backgrounds in Planescape (PHB backgrounds)
Rogue Modron race)
5e Factions [ edit ]
Al-Qadim- Land of Fate (useful for the Inner Planes)
Monster Conversions for 5th Edition
Kamikaze Midget/Jacob Driscoll
Why Planescape?
Planetouched 'race' (tieflings, aasimar, genasi, zenythri, feytouched, farspawn, shadowspawn)
Bariaur race
Githzerai race
Outcaste Modron race
Faction backgrounds
Cleric domain: The Great Unknown
Monk tradition: Way of the Dead
Paladin oath: Oath of Destruction
Warlock pact: Oath of the Winds (of Pandemonium)
Monk tradition: Way of the Immortals
Rogue archetype: Digger
To clarify, what you list as my "faction backgrounds" are not backgrounds at all, but completely their own thing. I did this deliberately because I knew about Jacob's solid effort converting factions using the 5e background rules and didn't want to recreate the wheel.
Great that you're keeping track of this stuff. Should be more from the fans once DMG releases!
I am not a very cautious poster. Edited.
Anyone else, feel free to post more links as they find them.
