Delta Pavonis, known natively as Aelycah, is the system which hosts the shyxaure homeworld of Delvasi. It is the center of Worldtribe space, serving as both a hub of shipbuilding due to its rich asteroid belt and a key point in the deep space travel network. However, the system's central star is an old G8IV-type that will soon slip into its red giant phase, eventually rendering its planets uninhabitable.

Astrography

Location

The Aelycah system is located in the southern celestial hemisphere relative to Sol, roughly 20 lightyears distant. Its closest neighbor is the red dwarf Sycasim, but it has jump links to eight systems: Sycasim, Çaylar's Star, Xynesor's Star, Qisuri, Qaytaral, Hmn Çelyth, Qaryn 7, and Qaryn 8.

Structure

The system's primary and only star is Aelycah itself, but the presence of Haaçayor creates slight barycentric behavior between the two. The inner system is bounded by asteroid belts on both sides: the metal-rich Saqorat Belt on the interior with its dwarf planet shepherd, and the carbonaceous Aelorauxe Belt on the exterior maintained by Haaçayor's gravity. Curiously, the planets within this region are almost all in binary pairs; Delvasi is actually the odd one out for having such small companions. Exterior to the Aelorauxe Belt is the outer system, the realm of the three giant planets and their surprisingly few moons. Beyond these is the wide, sparse Ysondir Disk: a comet cloud with a small number of far-scattered erimae that may have once been moons of the gas giants.

Ecosystem

The Aelycah system is the origin point of no less than three independent groups of organisms: Delvasigenia, which originated on the planet Delvasi; Theragenia, which originated on Thera and spread to its cobinary Taylo; and Xaiunegenia, which inhabit the cold ammonia-rich world of Xaiune farther out in the system.

Reality Check

The real Delta Pavonis system has one unconfirmed planet candidate: a large jovian planet with a low eccentricity orbit at about 11.1 AU; corresponding directly to Haaçayor. The star also has over double the metallicity of Sol, meaning the planets in its orbit are likely rather large and rich in heavier elements.
