Any in-depth mount/pet guides?

Are there any guides out there that show how to acquire all the mounts that exist? I’ve searched for a couple hours and the ones out so far (at least in English–the realm of what I’m able to search) but they only cover a few. I’ve dug through inven.co.kr a bit, but I couldn’t really make sense of what I’m looking at. If anyone knows any existing Korean or Russian guides I’d really appreciate it!
