After a few seconds, Karl found that it was easier to have the new feature form in all three spaces evenly, as an imbalance in them was going to cause him to have to alternate.
That proved to Karl that this was definitely something different than he had done before, as the other additions to the spaces he had been able to add freely to each of them independently, they were just decorations.
It was only after the basics of the new power cores in the spaces were in balance and properly formed that the energy increases started to spread between them, keeping the three focal points in balance naturally.
