The reason why I'm making a thread on this is simple: Jagex has never been known to put "nothing interesting happens here" on anything. Ever. Until now.

I found this on the new dungeon map update. If you look at braindeath island, it says that. Is something "happening" there? Is it a spoiler or a hint for a new update?(remember rest...or the brassica prime?)
The other part, which I don't know if it's new or not, is that the entire area is checker-boarded off. If I'm right about the checkerboard, that means that upcoming content is in development there. Does anyone have any idea as to what's there? Or did a Jagex mod just put that in for the lulz?
