The Mandragora Sector: variously prefixed with adjectives such as 'dread', 'troubled' and 'infamous'. A place so horrific that just tracing your ancestry back there might blight an otherwise shining career.
But just what is it about Mandragora that makes it so terrible? I may be missing something fundamental, but its position (as far as I've heard it) coreward of Calixis doesn't seem to put it anywhere of cosmic significance (I could well be wrong about this) and I can't find anything that explains why it's in such a state.
Or, indeed, what sort of state it's in.
I was wondering if anyone knows? Otherwise, it will be incumbent upon my GM to make something up to satisfy my curiosity, I suspect...
Perhaps it's some sort of massive pleasure sector that offers the most stunning women, beaches and cuisine imaginable, and its inhabitants live in fear of being overrun by noble playboys and good-for-nothing Rogue Traders, so whenever they do leave, they always prefix their beloved sector with some vague and terrifying adjective?
If each Sector is (I seem to recall) about 200 light years per side, then the "mystery" sector on the map would be 300+ light years away from the edge of the Calixis Sector. That's about 2,850 trillion kilometers... Doesn't necessarily rule it out...
