Cool Gravestone

Idk lol, I was flying my wyvern to load chunks for voxy and I came across this cool gravestone SW of Ragni in the moutains overlooking the Pigman Ravines Exit. There's a trail leading up to it and what appears to be a (non-content, but rather aesthetic) cave nearby, also, to the right a little, there was a mob. All of this was seperated by barrier blocks, so I couldn't get up to it though. Maybe its accesible through fruma.
Sorry for my clones.

...Hm? You've started, but...

...Well, well. Don't worry. The time will come, yes, the time will come. You will walk the path the wind took, yes. In time, in time...
