Soul Crystals begin as C-Grade amber gems that harvest soul energy to power swordsmen guards, then shrink to marble-sized remnants after overloading from mass deaths in ghoul generators, and finally evolve into F-Quality purple walnut-sized gems used to control dirigible house balloon power output. Their function shifts from passive energy harvesting to explosive overload protection and then to active rechargeable power regulation. The crystals' physical properties transform from glowing golden tendrils to non-glowing remnants to dull purple hues, while their utility expands from defensive powering to explosive safety mechanisms to mobile vehicle control.
