Yah, I went through 3,5 that one.
However, where do I go? I am southwest one sector but I can't see anything.
It will not are you to a new cluster of stars in double digit quadrants. Q(20,40) would be an example. It's smaller than Sol cluster, but I'm not sure of its size.
If you go there make note of the wormhole home ... It's a long trip to fly straight. You will need a ship with a LOT of cargo space. There will be alien wrecks to investigate, but be sure not to investigate one that is already being investigated by another player. That is akin to piracy and could get you in a world of hurt.
You will find lots of fuel this way, I won't spoil the other surprises waiting for you.
