Crouching Peg, Hidden Hole

D&D and similar RPGs are games are a weird mash-up of cultures and troped. knights from the Middle Ages, allied with Norse demihumans and Arthurian wizards fight monsters from Germanic folklore and Greco-Roman mythology. Then you add monks to that already weird mix.

Monks are inspired by the mythology and culture half a world away from the other sources of inspiration. Inspired/ appropriated. Monks also have a unique form of magic, unlike any other class’ power. Why can’t fighters or rogues tap into ki? Is it similar to arcane magic?
