Cruxwinds

I've just joined Second Life mainly for the sake of Cruxwinds, but when I search for it, no results,
and I've found no other way to get to it.
I suspect I may have to be enrolled with Cruxwinds to access it, but I can't figure out how to do
that.
I've seen fairly recent mentions of it, so I'm assuming it still exists on Second Life.
Thanks
