Our Lord Ditto died for your sins so that His prophet, this regular ordinary human child, could rebuild a society for Our Blessed Trainers to return to.
Yeah I'm not sure where you're supposed to go to get to Nuln. North around the dark lands I guess, but you're kind of pulled down into the Mountains of Mourn because somebody's always going to hold the last settlement in a province. I guess the second quest battle just gives Nuln to you lmao.
I'm playing with an alternate victory conditions mod, so it wants me to take the mountains and then ally with the chorfs (though I'll have to take Zarr Naggrund because the Servants of the conclave refuse to ally).
