about the paradise counterpart , I have a good idea :- How about you make it like the infinite Tsukuyomi /The Matrix ??? it will be low cost & efficient .... they will enter an eternal dream where they live forever and whatever they want becomes reality !!! they can even become gods !!! (of course , without any real power ...they will just believe they are gods ...) also , he will be able to access their memories , so any new knowledge or information or experience can be farmed regularly ... they will also continue giving him belief & divine energy in their dreams .... just like the Matrix ... and the best thing is , he just needs to create a foolproof illusion that makes them have what they want , he doesn't need to actually create things & fulfill their every need ...
Idea: A place according to MCs tastes that have the following system: -You are given choices depending on your achievements (leaving this open to plot for author) with the default choices being: 1- Leave here and serve somehow and leave a happy life (somewhat building Vallian Asgard of his own) 2- Work to receive perks on your next reincarnation such as good luck, power, being under the god of magic umbrella etc. -Gather power (or whatever needed) for the MC to branch across the galaxy and have not only human believers but other races as well making his own Vallian Asgard the better Asgard with diversity and technology not obstructed by Odin's decisions That is the gist of it, but it sounds cool and opens the plot a lot.
Why not a place where people live eternally in piece and spend their eternal lives in search of knowledge to further the glory(aka power) of their God. So MC can have an army of immortal scientist/mystics at his command.This fits well with his primary roll as a god of wisdom because knowledge is the wealth that grows the more you spend it.
I would have it be a mix for the average follower that simply live an average life and doesn't do anything to bad something similar to paradise they can imagine whatever into existence but only to the limit of a filthy rich very happy mortal. For heroic saintly followers something like after they pass on imbue their body with some divinity energy like an asgardian with Odin force maybe use a heavily diluted version of the tablet formula to grant them superhuman physical abilities.
