Hi Ellie!!

We are all an anxious as you to find out those same answers! The authors wrote the VV1, VV2, and VV3 storyline at the same time. They will either reveal the mystery in the next chapter or only some and extend it further into another chapter.
For instance, one of the things we found out in VV2 was where the cave of VV1 leads to. I'm sure that we will find out MUCH more in the next chapter!!

One way or another: Welcome to the forums!!
