~5 billion years ago — The Nary System forms from a dense molecular cloud in a stellar nursery. Gravity causes gas and dust to collapse into the massive blue giant star Nary.
~4.8 billion years ago — Protoplanetary disk forms around Nary, gradually coalescing into the rocky planets Veltrion and Kaelara, and the massive gas giant Zurnath.
~4.7 billion years ago — Moons like Teryx (around Veltrion) and Syrel (around Kaelara) form either from capture or accretion of debris.
Present: A Young, Dynamic System
Nary shines as a hot, luminous blue giant star, emitting intense radiation that shapes the atmospheres and surfaces of its planets.
Veltrion experiences extreme volcanic activity and dust storms due to its proximity to Nary.
Kaelara has a more temperate climate, possibly with stable ice caps in deep craters.
Zurnath remains a gas giant with spectacular rings, dominating the outer system.
The moons orbit stably but experience tidal effects from their parent planets and Nary’s gravity.
Future: Toward Stellar Cataclysm
~1 billion years from now — Nary begins to burn through heavier elements in its core, becoming more unstable and increasing its luminosity, causing harsher conditions for the inner planets.
~2 billion years from now — Outer planets and moons begin to experience changes in orbit due to the star’s mass loss and stellar wind.
~2.5 billion years from now — Nary reaches the end of its life cycle. Given its mass and type (blue giant), it likely goes supernova, a cataclysmic explosion that will:
