The Halligan Brothers 2

I played this game called INTRODUCTION https://www.roblox.com/games/1255949484/INTRODUCTION and I joined it, there was 2 people waving in a statue, and a grave, I moved out the map, which was nothing and a Grave infront of the statue opened up.

I jumped in, but no one else did so I guess only I saw it open and I guess I triggered it to open. So I jumped in and I felt a bit scared, just as I was about to reset, I was teleported to a game called PART ONE, I immediately left, but what I saw was that there was a dinner room kind of and people at tables were looking at you, I think those people were admins.
