"Yeah. I really should've thought of this earlier, but it's hard to think on a cosmic scale. What seems likeliest to me is that planets capture gates in a straightforward way, and then I have no idea what happens if you open a gate on a moon or a jumpship. But since it's conceivable that all gates in this world are now anchored to the rotation of this particular planet, or something similarly inconvenient, the first gate you open not on this planet should probably be in an uninhabited system just in case."
