a manga my ex gf recc'd to me but i never really managed to read all. very subconscious collective idea, the tower of "tests". also in legend of mana there is the tower of leires. https://en.wikipedia.org/wiki/Tower_of_God
Oh nice! Yeah for sure, theres definitely a lot of “this tower is a plot device for the caracter to overcome challenges” in stories. I’ll have to check out the manga
