I have been playing around a bit, I'll experiemnt some more though. I have been using other (custom) StellarAbilityTypes and though I can't swear to it, yet, it looks like one system decides to make a WP, and pokes it through into the next, using it's own choice from StellarAbilityTypes to determine wormhole properties. But, I think this may warrant further investigation, so when I get time I'll set up some test data and generate a load of maps.
