I want to make mod to introduce my dream-faction of undead (Probably with Wraith Blood)
1) Are there any guides?
2) How to do, as selectable nation perks (best if they all are 0 cost, so I can just toy with them around):
Eternal Sleep - No natural people gain
Dead Rising - People gain per death shard + max effectivness slave lord (Yep, this one is like in undead from DLC, but my guess is that it's hard-coded, and I don't have cash to get that DLC, I got the LH as gift)
They are Endless - No people limit in cities
Use all you got - Production gain per grain (Best if 50% ratio, 4.5 production from perfect 3/3/3 tile would be cool)
Some of these could be fun to play with even without roleplay. "Use all you got" is probably worth 2 points due to how well it could accelerate city growth in normal factions.
