In-Births are capable of using the power of Manifesting to give the EXS stored within their Vessel a shape, in the form of an EXS ability. Overuse of EXS abilities or gathering huge amounts of EXS within their Vessel can cause an In-Birth to lose themselves and turning into a Void.
Voids are driven by instinct to consume EXS and can manifest themselves in the presence of large concentrations of it.
It would also appear, based on story dialogue, that characters from other universes such as Eltnum and Akatsuki do not require EXS to use their abilities, though they still contain it within their being and are thus vulnerable to consumption by Voids.
