I posted again. As you can see, it's the "Vanguard in space" me and Pro talked about months ago. In my mind, it's the beginning of a series of mini "Lost" tales, concentrate into this one issue.
How they did get there will be explained by the end of the issue.
As you can see, they now are in space (and in the future, as in the present there is nothing in space like the thing I described).
I have no absolute idea of what they will be doing there, so everyone can follow my post absolutely freely. By the way, the cavern would allow anyone to jump exaclty where the others are, so, Pro, (or Danny) if you want to have your guy (or squirrel) joining (or stumble upon) the others, do it like in the old times, when we were not so sophisticated to how have a character joining the others. He enters the cave, and end wherever the others are.
