Rithris appears as a towering lamia-bodied goddess whose lower coils are braided with living roots and slow-growing vines that bloom when she is calm and retract like bristling thorns when she is wrathful. Her human torso is wrapped in a lattice of pale bone filigree that looks like a ceremonial ribcage. She wears a feathered mask at her hip, not on her face, carved with two opposing faces: one inhaling, one exhaling. Her movements are deliberate and unhurried, like someone measuring breath; when she walks her coils whisper against the ground and leave faint, half-luminous footprints that fade after an hour. Unexpectedly, her left hand is callused and stained with soil while her right hand is unblemished and faintly warm to the touch.
