Tullytoft Aster is the designer handbag of stryx. Descended from a long line of famous smooth-gaited racing studs, her kite-like build affords her unmatched agility and control in the air, while also providing a smooth ride for the refined lady. She loves being brushed and flattered, eating high-quality meals, and generally being pampered with all the attention worthy of a stryx of her pedigree.

She is the personal mount of Tiffany Mary Prior, a teenage patrician girl currently working as an unpaid intern on the ranch. Aster's refined tastes often put her in conflict with the lowborn stryx at Hibernia Acres. She abhors violence, filth, and cheap mash, so being dragged out to the boonies and forced to mingle with the commoners is basically her personal hell.
