[BTR] Locked to Torchwood Chicago, and to Martha Jones

So, something identifying itself as the Kashtta Tower showed up on the journal networks, writing a locked entry to Martha, a bit ago. I have a few questions about this, as I can imagine Martha does, too.

Mercury, could this tie into the journal experiments you've been doing? Failing that, Owen, Mio, anything you've heard from the Tower's directions which might shed some light?
