She desires to use the Apollos lens to conquer the world, and appears to be prepared to backstab her partner in crime Blados in order to obtain it for herself. Chalis usee the Lens to cause the Grave Eclipse, which floods an entire continent in darkness. Blados and Chalis are forcibly merged with Volechek, turning him into the Chaos Chimera, which reverts back to normal after being defeated, however Chalis appears to survive, since She and Blados are still able to talk to the party even afterwards.
Chalis is a level-headed woman with alluring charm that uses her bewitching beauty as a weapon and gets close to the important persons of other countries. The way she acts as if she can see through everything is ominous. For a currently unknown reason, she and her country contact Matthew and his group and seem to be making use of the protagonists.
