I'm going to start here with a bit of the history of our world. Many eons ago, on some other world, a group of heroes known as The Blue Moon Bastards retired from their adventuring career by saving their world and the life of the god Bahamut, and in the process became gods themselves. They built a new world, and that world is the one we know as the Zeitgeist world.
Those gods:
Dana, the goddess of Earth and Life
Wilik, the god of Fire and Time
Harann, goddess of Air and Space
Shiver, god of Water and Death
Vaic, god of Trickery
and Erich the betrayer, who sided with Tiamat in the final battle, but still had a role to play in the new world, adding the necessary chaos to agitate everything into being.
They were the true creators of the world. All other gods are either creations of their own or were spawned anew by the world and its inhabitants.
And then all the standard Zeitgeist history happened, up until the year 400 or so, when King Lorcan of Risur was tricked into sacrificing himself on Cauldron Hill. The Red Contessa ruled over Flint for 60 years, feeding many souls to the mountain until King Aodhan of Risur returned with a stolen Danoran steamship and shelled the witches of Cauldron Hill into submission. And then we're back to a fairly normal timeline. Zeitgeist happened more or less as expected. The details are in the other thread.
Now the world has the following planets/planes:
Jiese
the moon of Ascetia, which itself has the moon Av
Caeloon
Mavisha, with its moon Shabboath
Urim and its clockwork moon, Teykfa
Apet
Bhoior the space turtle who wears the ring of Reida on his head
Nem and its salt moon Amrou, where Sargon of Uggat, whose father was the cupbearer of Ur-Zababa keeps an eye on the orderly passing of souls.
Rules (and notions) for the world as a result:
- Precision technology is theoretically possible, but something has disrupted the link to Jiese of late. This is to explain the lack of technological advancement in the past 100 years. Guns and mech suits and airplanes exist in the world and can be found as treasure, but they can no longer be built.
- Eladrin have lost Misty Step and instead have Memory of 1000 Lifetimes, as Av is reflecting Ascetia, which holds the history of the world. It's possible the dark side of Av reflects the "bad" history in which the Constables failed to stop Nicodemus. Or possibly it reflects the future held in Reida.
- Falling damage is reduced by the result of an Acrobatics check as everyone falls like paper.
- Islands still hold impenetrable secrets
- An underdark now exists, together with Cthulhu-esque things in the ocean. When the Eladrin race was reborn after the events of the campaign, some came back as Drow. Probably the more evil ones.
- Gold blocks teleportation.
- Brass does something time-related but I haven't figured it out yet.
- Apet still restricts movement in and out of the solar system. This lines up wonderfully with the lack of planar travel in Ptolus, and I can sub in Apet for the one moon whose name i've forgotten in that setting.
- Reida still gives strong prophecy
- Bhoior allows sounds to echo through time.
- Nem gives extra power to noncorporeal undead, while Amrou gives extra power to mundane counters to the undead, so I'm going to do the following with Turn Undead:
Anyone can Turn Undead once per day, with a DC equal to 8+CHA mod. It only works on corporeal undead and never causes destruction.
A Divinely-Channeled Turn Undead works worse vs incorporeal undead (save with advantage), and better vs corporeal undead (normal save, but are destroyed as though the cleric is 3 levels higher).
I'll add a feat that gives people proficiency with Turn Undead (Clerics already have it) and allows a second use per day.
Alright, that's it for now. Still to come: new political environment and new characters!
edit: non-cleric players did not want to have to track Turn Undead rules and cleric player wanted to still be special.
