Itechkav System

The Itechkav System

The Itechkav System is a star system located in the core of Asharbyel, and is one of the most important systems of the Agshu'urach. The system is centered around a late-K dwarf, Itechkav, and contains 9 planets. The fourth planet, Onbutlal, is the homeworld of the Yalan, one of the two intelligent species constituting the Agshu'urach, and is one of the two capitals of the Agshu’urach.

## System

The Itechkav system contains 9 planets. Most orbit closely to Itechkav in resonance orbits, making them more stable. Many of Itechkav’s planets have been terraformed, and as a result of low metallicity all of Itechkav’s planets are very small.

The Itechkav system is generally divided into two areas: the inner and outer system. The inner system is comprised of the first 6 planets, Llöna, Ugnavey, Molmin, Onbutlal, Keaw and Eival. These planets are locked in resonances, keeping their orbits stable. The outer system is made up of the last 3 planets, Guwa-Umi, Hmyyt and Upewnu, which are all more massive gas dwarfs far from Itechkav, with small moon systems. There used to be several asteroid belts around the system, but these have been mined away.

The system is naturally teeming with the life. Out of its 9 planets, at least 3 (Onbutlal, Eival and Hmyyt) are naturally life-bearing. Life spread to every single world in the system via panspermia, except for the innermost planet Llöna.

### Itechkav

Itechkav itself is a fairly normal star in Asharbyel, a late K-dwarf of 0.36 solar masses. As a result of Asharbyel’s extremely low metallicity, Itechkav is much hotter than a star of its mass at normal metallicity. Itechkav is about 33% the size of the Sun and has a surface temperature of just under 4,000 K. An incomplete Dyson swarm is present around Itechkav, as well as multiple orbital rings.

### Llöna

Llöna is the innermost planet of Itechkav. It is a very small desert world with a thin atmosphere, and has been extensively mined for resources, which have gone into various structures around the system. There is an underground layer, located in the upper crust, which is much more habitable than the surface and climate-controlled, which is where most of Llöna's population lives.

### Ugnavey

Ugnavey is the second planet out from Itechkav. A relatively hot world with small lakes of water, Ugnavey is the hottest planet in the Itechkav System to harbour life, which was transmitted from Onbutlal via panspermia. There is a large population on Ugnavey for a body of its high temperature, mainly located in large indigenous-life-free climate-controlled domes and huge underground complexes of caverns.

### Molmin

Molmin, Itechkav's third planet, was the first planet to be significantly altered by the Yalan, quite some time ago. Initially, it was a barren desert world with a thin atmosphere and with a bit of terrestrial life. However, as the Yalan expanded they decided to terraform Molmin. The result was very successful - a transformed world, more like Onbutlal, where the Yalan could live without any equipment. The indigenous life was of course genetically modified to live in the new atmosphere. In the present day, Molmin is a tidally locked earthlike world, with oceans covering much of the surface, and a very large population throughout the planet.

### Onbutlal

Onbutlal is Itechkav's, and perhaps even Asharbyel's most important planet - the cradle of the Yalan civilisation, where everything began. On this tiny rock floating in space is where the galactic-spanning Agshu'urach first took hold, first spreading to nearby planets, and then to other alien systems. Onbutlal is also one of Itechkav's 3 cradles of life, the others being Eival and Hmyyt. Today, Onbutlal is a thriving life-bearing world with a huge population, both on the surface, underground and in orbit. Huge habitat rings orbit the planet with many billions or even trillions of individuals.
