Info

After parting from Ausar and experiencing a period of confusion, Osiris was encouraged by the Administrator to take a step forward on the path toward becoming her new self. Still as kind and gentle as before, yet now more determined and courageous, she is resolved to grow stronger and to help everyone in her own way.

Only a small, delicate child when she first arrived, it was hard to imagine such a fragile thing could actually fight the Visbanes. But Osiris has proved herself by her efforts and passing Aether Gazer's difficult training process to graduate alongside the likes of Verthandi as one of Aether Gazer's newest Modifiers. "Osiris has a habit of throwing everything she has at any mission assigned to her to the point I'm worried whether she is over-doing it". Shu tends to come down a little harshly on Verthandi, yet always seems ready with a kind word for Osiris or expression of concern for her well-being. Osiris is also probably the most popular Modifier around HQ, or at least seems to have cultivated the strongest and widest social network among her fellow Modifiers owing to her generally friendly and uplifting personality. She treats everyone gently and will discreetly offer to help and prioritize any struggling colleague, which is why everyone has taken to the affection nickname "Lil' Osi".
