The 3 Sparks.

She didn't tell him anything about Authority. Not even the most important information about how to get the spark of power. She ignored his question and instead went on to speak about the various stages of realm trees.

"Realm trees are not identical. We were created equal, but because we had varying potential for growth, we turned out differently. Each realm tree starts out as a seed and grows into a sapling. At that stage, we are small and in a vulnerable state. We are small and weak, so most small realms don't survive. They can't resist world gods yet, so they are hunted by world gods."

"The ones that survive to maturity do so by luck. The void universe is vast, and small realms are hidden. If they can't be found, then they will surely survive. If they are lucky enough to survive into mature realm trees like me, then they can resist world gods."
