Peer Star
餘星
The relational role of a star sharing the Stellar Regent's phase — the equal, same-kind relationship of alliance or competition.
A Peer Star (餘星) stands in the "same as me" (同我) relationship to the Stellar Regent — the Five-Phase role of a star sharing the self's own phase. It is the relationship of equals: kin, allies, and rivals of the same kind.
It is one of the five star-relations classifying every planet by its Five-Phase relationship to the chart's ruling star: Benefactor (generates me), Expression (I generate), Conquest (I control), Challenger (controls me), Peer (same phase). Each is a relational role defined against each chart's own Stellar Regent, not a fixed planetary quality.
The Peer Star shares a root with the Peer Archetype (餘格): when the Imprinting Star is a Peer Star, it shapes the consensus-reading personality — the one whose first reference is what everyone else thinks. "Peer" is chosen so the star family does not collide with the Four Shadows' use of "Shadow".
