This is a missable achievement for watching several of the Cultural Insights around the area of the Forest. TBH, I am not sure which other Insights are bundled with this one, but because there was no solution on this achievement, i wanted to post the one that I missed, "Rebirth & Naming" as it's easy to do and may be the one you missed as well. Chapter Select "Forest". I do not have a video but will link the one i watched to help me find it. Please someone, embellish on my solution as it's quite lacking. Link to clip: credits go to the maker
