This is the exact same place as Wasters, except this will have nothing to do with the Wastes. Everything is contained inside Anchor; the dungeons, monsters, and the effects of their dead gods don't affect Oasis and anywhere else in the setting.
Justice god:
You'll see his divine fury when he is resurrected. Probably involves fire. And bullets. You basically have to choose between complete lawlessness where anyone anywhere can die and no one gives two shits, or complete law where jaywalking is punished with hereditary community service.
Undead and monsters:
When you die (like get shot or something), you weren't really alive, so through some magic BS you're undead. You can think and feel fully, but you are always overcome by insatiable bloodlust. They will kill anything without remorse, then cry when they come to their senses and see what they've killed. They also look like zombies and skeletons.
Monsters can't feel or think. They are just manifestations of strife and chaos; rock elementals, giant pests, trolls, etc. They're not animals, plants, or any other type of life since nothing can live. They're practically forces of (un)nature.
Light god:
Banish all the monsters. Personally, this to me is the most B&W, morally, of all three gods. Getting rid of the monsters basically helps everyone and harms no one.
Life god:
All the undead will finally and truly die, but there will be no undead ever again. Also, people can conceive again! Of course, the gene pool is horribly messed up thanks to all that cloning and mutation, but a few generations after and it'll be relatively clean. All the undead communities and families will die though.
Basically, I made for this so that you won't be a paladin of pure good and righteousness, but more a paladin of the lesser evil. This also all applies only to this game. The Shifting Wastes is home to countless of civilizations with their own unique stories.
