Here's some shots from Stellarium of the area between the three constellations taken our date when Kahina visted Earth last year, her real date 3302 and our now for the sake of it.
There's the theory she went to Earth to get a bead on something. As you can see the Heart&Soul appear in the triangle between the queen, the giraffe and her daughter's hero. Sadly the stellarium screenshots aren't good enough for detail work.
If I was out that way right now I'd be looking at B stars and specifically B5's [the stellar extinction idea] in that bit of triangle of EAFOTS that intersects with Heart and Soul and patrol lines. Dead stars, dead worlds, strings of b5's or dead and suspicious elw and alw things around there. And how the mythy stuff fits,,,,
Another way to approach it is guessing what processes Drew might have gone through to place this mystery before the game came out and then when the ED galaxy was actually made and specific stuff could be crafted.
O well back to the drawing board,,,,,gonna try one note and maybe make an actual mandala of all this stuff,,,
