"Forgotten Realms" - if I ever saw one:
Akkadian Empire - to the surface:
"Clear records of tunneling operations extend back more than 4,000 years – Assyrian carvings show engineering units belonging to Sargon of Akkad (who reigned between 2,334 and 2,279 BCE) undermining the walls of enemy cities. American troops attacking Al Qaeda positions and pursuing Osama bin Laden in 2002 discovered a massive tunnel complex connecting the natural Tora Bora cave formations in Afghanistan. "
