The energy is what they came from, I see it as a mass of indescribable something or another that for now is the source of the threads, but that does not actually interact with the threads beyond their creation. So, the threads are made of the energy, but they are more inert and moldable than the energy itself, making them far more easy to work with than our beings trying to use the battling mass directly. That is, if you approve of the idea.
