This question may have been asked before, and if so, I apologize.
Some more questions:
What would the dominant language be in this land of the dead? Would anybody have any hope of communication unless they were placed with people from their time and place?
What food would the most people be used to eating? (Rice or wheat, I'd guess?)
If a pan-afterlife fight broke out, what would be the most common form of attack and defense?
hi OP. Can you scratch your last para re the "pan-afterlife fight": respondents are not permitted to speculate here per subreddit rules; you might post that one in /r/HistoricalWhatIf
