So I just finished the Pilgrimage mission with 10 planets in my solar system. The god said something to the effect of "You managed to protect 10 followers! Remarkable!" Then he told me that I've been blessed by the Holy Hole, and now my planets are all surrounded by a black aura that looks a little like the aura around antimatter asteroids.
What does this aura do? Does it have an effect on my solar system, or is it just there to look cool?
