I was doing the caves in Cyrodiil for the skyshards, as well as exploring all the spots on the map which looked like buildings. I then came across this strange rock formation with a hole...
this was the result. (mic sound is low, but you really only need to watch it to understand)
I must admit this was one of the coolest things I have ever seen in a video game. Whoever designed this needs to do more of this all across Tamriel.
I am also fairly positive it's bugged since you go through that limbo of falling through the map.
tldr: You can jump into a hole in Cyrodiil and you fall through a cave and end up inside of Cracked Wood Cave, giving the dungeon 2 entrances.
