Matriorb

A greyish ball covered in what appears to be Troll horns. Found in the abdomen of Kanaya Maryam's Lusus, a Virgin Mother Grub. It must be protected and used to hatch another Mother Grub. It will likely prove a plot-centric device. It's practically covered in Weird Plot Shit. Presumably it could be used to save the troll race after the completion of Sgrub. Kanaya safely stores the orb in her Chastity Modus, not to removed until the timing is exactly right.

She has probably used it in alchemizations, as she is HS 4478 (later seen) wielding a chainsaw with troll horn teeth.
