Whilst some of you are having fun out in the dark, with your maps and your scans and whatnot, there are those of us (or possibly only me), who think that the trigger for discovery lies back in the Bubble ('...depends on who goes looking'). Sadly, all my theorizing has so far come to nought, so I figured I'd put my ideas out and see if anyone can make a connection that I've missed.
So...
There appears to be a mythological thread running through the clues, with Persephone being the primary link. She has ties to Hades and the underworld - the gates of which Virgil refers to as 'formidine'. There is also a connection to Ares/Mars through his son Deimos, whose Roman equivalent is 'Formido'.
In an additional link, the contraband liquor that Kahina was given on her trip to London is 'Gerasian' - from the planet Geras, which is named after the Greek god of Old Age. Does this tie in with the old woman who gave Kahina the Formidine story in the first place?
Based on these tenuous connections, I've been ligging around the Bubble with a hold full of Gerasian Gueuze Beer, delivering it to the Sol, Persephone, Avalon and Tartarus systems.
Oh yeah, Tartarus is the part of the Greek underworld where the Titans are imprisoned - Where did Kahina have an appointment? On Titan...
Unsurprisingly, none of this appears to have achieved anything.
Anybody have any better ideas?
