>>12091469Well there were Yamasks there, yes.
As for unique pokemon, I don't really think so, aside from the fact that Yamasks are usually native to Unova.
Same with Golurks. There were some lumbering around there as well.
I caught one of each, but otherwise left the place untouched.
Turnback cave is just all together weird.
It just seems like it has a bigger purpose.
After all, Golurks are said to serve those who created them.
Could those laid to rest in the cave have wanted it protected?
