Having a central star with jumps in-plane but also up & down, none of which are mutually in-range, makes for a critical nexus. The 'truck stop' planet. Connects the known space sector map with the north and south exploratory maps.
In an exploratory sector (South, Rimward, *and*Trailing, iirc, so far from the beaten-path, an unrecovered sector), we had centuries-old (pre-collapse) Imperial Scout Service notes on the 3 possible intermediate-jump systems; Scout was apparently not impressed, their notes were one word only each:
Water.
Sand.
Ice.
For refueling purposes, we picked Water, as we didn't fancy chopping or melting ice; may have missed discovering the Spice planet? ;-)
