Na'el and Matthew

Despite being siblings, Matthew and his younger sister Na'el have very different outlooks on life which reaches a breaking point after the death of innocent children close to Na'el. Matthew is able to understand that the soldiers of Keves and Agnus are mere slaves to Moebius and seeks to free them, while Na'el blames them and dismisses them as blood thirsty savages not worth risking the lives of those she cares about, condemning them despite being victims themselves.
