Heroes of the Orient by Marc Altfuldisch is easily one of the worst "modern" OA supplement I've seen.

It's lazy, reductive, and does little to progress the hobby beyond the Asian stereotypes of the 80s.

Dear white gamer, "make the Orient your own". #dungeonsanddragons

This dude also wrote a "Monsters of the Orient" book and straight up included the mogwai from the Gremlins movies.
