I need to be conscious of the energy drain. The force bubble is directly connected to my SolCharge, a crystalline vial embedded in my chest. It was installed for me during one of my travels some years ago by the gem-based culture of Glintara on the planet of Lumicryst. I still do not quite understand how it works. The crystal of the vial can harness and store energy. I usually just charge with the sun because it’s so quick. A full moon or a bright moon works, as well, although it takes a bit longer.
I don’t know if everybody’s SolCharge looks the same. The liquid in mine is a sort of amber color. The consistency is viscous, almost like honey. As I use the energy, the liquid depletes, and I can see the level reduced in the vial.
