Caleb speculated about the total energy contained within the soul in his writings, introducing the concept of a "species baseline magic power," which described the base amount of magic power a species possessed even without soul training.
Fisher quickly realized this might have been the source of the technology that Philone had obtained from the manual, as well as the theoretical basis behind his bizarre ideas.
Fisher guessed that Philone's original idea was to allow the soul to release energy, then wait for their magic power to be depleted before self-repairing, and then wait for the next use. However, this was no different from engraving magic, consuming a lot of time and being extremely inefficient, otherwise those magic items would not have been so expensive.
When this approach proved unworkable, inspired by Soul Loss, Philone went to the other extreme.
