Monster Hunter World Part 39- Master Rank Quests Begin?

Seems I am missing a video so this is now 38. I seem to recall that I accidently went to the the Iceborne DLC but I didn't do any quests. But obviously this is a little bit further into it than it should be. So the video is gone and I don't know where. Corruption, misplacement, or Aliens? Who knows because I don't.

NVM I found it
