The Tendril system is a stellar time bomb with a very long fuse. The blue star Tendril is a markedly unstable F1 star-as the star nears end of its life, its intense solar flare activity grows slowly stronger. Roughly every 67 days, solar flares engulf the star for 13 days in a period that system natives call The Burn. After each flare-up, the solar activity returns to normal levels for about 67 days. According to the most reliable measurements, the star won’t be going nova in the next few thousand years, but scientists are at a loss to explain the star’s strange yet steady pulse.
Until its star goes nova, the Tendril system will remain the gateway from the Stellar Ring to the center of the Verge. To Arrivers, it bears a strong resemblance to the kind of place they’re used to. As the first settlement in Verge space a century ago and the first to be contacted after the Second Galactic War, Tendril is also among the most civilized systems in the Verge. It is the Verge’s third most populous system, a sprawling, asteroid-filled area of space whose worthwhile holdings-moons, mostly- were claimed by StarMech before the war. The vast majority of Tendril’s immense mineral wealth remains unclaimed, though many spacers stake informal claims, mine it, and process it be¬fore anyone notices.
Despite Tendril’s ideal location, the system is unlikely to dominate the politics and economics of the Verge. The first problem is the star’s instability. The second is the system’s lack of an easily habitable planet, or even an easily terraformed one. Tendril bathes its inner system with a high level of radiation. The ring of space that’s warm enough to support a habitable planet is too dangerously radioactive for most sentient species to endure without special equipment.
The closest planet to Tendril is Delphin, a sandy husk with an atmosphere of carbon monoxide and carbonyl vapor. Its sole importance today is the Land’s View terraforming station. Land’s View is one of the most ambitious and long-term terraforming operations in explored space. Sperous, a hellish planet cloaked in clouds and blanketed in intense heat, gives Venus of the Sol system a good name. It’s home to nothing and no one,- even exploratory probes rarely reach its acidic surface. However, Sperous does boast a moon, Alaundril, capable of supporting life. Atlas, a cold rock-planet orbited by Nova Station, and the Cyra Belt close out the inner system,- the gas giant Pox and its many small moons lie beyond.
