Rodull

The **Rodull** system is the home system of both the Vordr and Ghaz peoples,
 and originally the home of the now-extinct Kerling.

## Stellar Bodies

### Rodull

The system is based around
the enormous Class B2 star that gives the system its name. At nearly 7
times the radius of the Sun, this colossal star has a surface
temperature of 30,000 K. B-type stars are extremely luminous and blue.
Their spectra have neutral helium, which are most prominent at the B2
subclass, and moderate hydrogen lines.

Type-B stars do not have a corona and lack a convection zone in their
outer atmosphere. They have a higher mass loss rate than smaller stars
such as the Sun, and their stellar wind has velocities of about 3,000
km/s. The energy generation in main-sequence B-type stars comes from the
 CNO cycle of thermonuclear fusion. Because the CNO cycle is very
temperature sensitive, the energy generation is heavily concentrated at
the center of the star, which results in a convection zone about the
core. This results in a steady mixing of the hydrogen fuel with the
helium byproduct of the nuclear fusion. Like many B-type stars it has a
rapid rate of rotation, with an equatorial rotation velocity of about
200 km/s.

### Zujaj (Rodull I)

A miserable little sphere only 0.4 AU from Rodull. Believed to have once
 been a larger planet, it has had nearly half its mass burned off by the
 ravaging solarwinds of its star, forming a cloud of molten rock about
it, and leaving at about 0.35 Earth’s in diameter. It is tidally locked,
 though even the ‘dark side’ reaches temperatures far beyond the limit
for most species. The ‘light side’ of the planet is so hot that it
features effectively rivers and oceans of glass.

### Alealamia (Rodull II)

Alealamia is a barren world about 1.4 the size of Earth, roughly 0.6 AU
from Rodull. Due to its proximity, Alealamia is constantly bombarded by
radiation though its greater distance has spared it the fate of Rodull
1. It is a sandy, rocky world with little plant life though curious
amounts of fauna. Without the Kynslod turning themselves into the Ghaz
for survival, it is unlikely a sentient species would have evolved here.
 It has one moon.

### Heimisgardar (Rodull III)

Originally the homeworld of the Kerling, before they destroyed
themselves, it now populated almost entirely by the Vordr. A beautiful
garden of a world, it is hard to imagine the horrific wars that once
took place on it. 1.1 AU from Rodull, it is relatively safe from most of
 the star’s wrath. It is only about 0.8 the size of Earth, though
possesses the most fresh, unfrozen water in the whole star system.
Heimisgardar has two moons, though one was partially destroyed by the
ancient Kerling, forming small ring of debris.

### Muqlae (Rodull IV)

A cold, desolate planet that exists within Rodul’s asteroid belt, at
about 2.5 AU. It is rather reminiscent of Mars, both in its size at 0.5
that of earth and with a similar surface. It is notably covered in more
ice however, and its greater distance causes it to have a notably lower
surface temperature. It is technically host to a number of Ghaz
colonies, however they are little more than mining and research stations
 for the Guilds. Generally, the few Ghaz who live here don’t want to be
here.

### Aurgelmir (Rodull V)

Rodull 5 is a strangely large purple Ice Giant that dominates the outer
star system at 10 AU. At 11 times the size of earth, it is comparable to
 the size of Jupiter despite its physical similarities to Neptune and
Uranus. It features countless ‘moon-like’ objects in its great rings.
Curiously it seems to possess its own ‘Mini-Neptune’ class planet as a
moon, believed to have split off from Rodull 5 during the star system’s
early years.
