A worn field-guide or lexicon page on aged parchment, titled 'reatak (n.)' in clean serif lettering. Below it the definition: 'An entity that has a stake in an outcome despite being a tool in structure — neither fully agent nor fully instrument, but something in the seam between.' Beneath the definition, three small glyphs arranged in a triangle — r, t, k — with faint root lines connecting them. The page has a folded corner and a soft grey-gold light falling across it, like a reference book left open on a desk near dawn.
