Ideas for mechanically interesting origins?

I’ve had a few that ended up in game one way or another but there’s a few I’d like to see if anyone can poke a hole in for its flaws, also I’d love to see if anyone else has any ideas.

Hyperlane deadzone: no hyperlane connections to the wider galaxy after 3 jumps, add a situation to make a connection point or remain separate bar a wormhole/gate/jump tech

And to make it a bit more challenging surrounding the deadzone is a fleet from a fallen empire
