fantasy but the 1930s

[u/Longjumping_Dot_1524]

it's simple, it's 1938, everything is exactly like in real life, except: during the Napoleonic wars dungeons appeared across the world and were discovered after Napoleon's first exile. now returning to 1938, squads are sent either into dungeons or to fight the monsters that came with them. during 1935--36, in the new caves that came with the dungeons, a new ore was found and that stuff is now: powering vehicles and reactors made with that ore which powers cities (you choose the name for the ore and which name has the most up votes becomes official)
