Idk if this is a hot take or not. yall tell me.
The best way to worldbuild is to put players in it. you don't need 2000 yrs of history. pick a date for the setting build a little bit to make sure there is a storyline for the plot but ultimately getting players in your world will help build the world & make it way more interesting than just you by yourself. it may be "Your World" but it's their Setting.
That may explain why Tor-Samil now has almost 30+ players that have been thrown at it
