Stellar geography - what's that bit of Galaxy Seven called?

[Malacandra]

Hiya. A possibly dumb query, but I'd rather waste everyone else's time than do my own damn research and I've not managed to find out the answer for myself. Galaxy Seven has a bit torn off in the bottom left corner - twenty-odd systems that are out of Witchjump range of the rest of the galaxy. Has anyone named this feature or do I get to christen it for the story I'm writing?

Many thanks,
Mal

Collectively, they're often called The Rift Worlds, and the gap is known as The Great Rift (from ClymAngus'  Vector Maps).
However, you can name them anything you wish. They are reachable, btw - all you need is an ideal victim.

My word, that was fast!

Much obliged (and you know, I swear I'd seen that before, too).

That's our Cody! I wouldn't recommend you challenging him in a duel....

But out there around the eight there is a lot of strange things that that seem somewhat familiar and very alien at the same time. It is a wise commander that keep their wits about them!
