Energy-verse

Persephone picked up one of the blades of grass and watched the energy trickle out. She cupped her hand under it, so it pooled in her palm. Cautiously, she started playing around with it. The more she did so, the more a bond seemed to form between her and the green light, to [Clara] it looked almost like a bond of trust. As the corners of Persephone's mouth started gradually turning upwards into their usual position, [Clara] too found herself cheered by this little spectacle, even letting out a giggle. The little sphere of life-force was shining very brightly by now, in symbiosis with the hands turning and weaving it.
After a while, Persephone nuzzled the sphere lightly, and passed it back into the shimmering field.

"At times, you can carry the energy out of here. But you have to be careful, oh-so-careful, and, more importantly - care. If you're an unworthy bearer, it will be obvious. You won't be able to handle the energy and it might just escape and wreak havoc on a cat or something. Which would be bad.
Anyhow, you can keep it in anything that fits its element. There are thirteen of them, I'll get to that in a bit. If you pool one kind of energy into a different element, it gets weakened, or, if the element is sinister enough, cancelled out altogether."
