Ati is a grippli denizen of the Abyssal Forest of Khaar, where she maintains and harvests a grove of Verbena trees for her tribe. She is immune to the toxin, and can even produce it within her body, where it coats her skin. She has a mutation that allows her to draw nearby toxins into her own body, where they are repurposed, and with effort can even use this ability to draw toxins out of others.
Ati spends most of her time tending to the Verbena grove or exploring with Ba'Tolo, a baneback with a potent toxin in his skin. Luckily, Ati is immune.
