I didn't mean to insinuate that it was plagiarism or anything like that; this is likely just an example of how culture teaches us that certain characteristics fit archetypes. It's like how the El dra zi
resemble the Ogdru Jahad
, but rather than the former copying the latter, they were both inspired by the "Great Old Ones" from the Cthulhu Mythos
I guess there's just something about extra-long forearms that screams "I'm a being of great, dark power!"
