Voixer is a Point made out a remnant of Celesteal combined with the nothingness of the void. Voixer is devoid of personality because they are nothing. They wish for nothingness to spread until all is gone, until they realized they we're being took over by Celesteal. Which made him realize of what he's made and that they should not be able to change appearance because they do not technically exist. They decide to destroy their physical form and return to non-existence, taking Cyalm with them.
