Pavala and Haki
Pavala and Haki, a collaborative worldbuilding project for those interested. It takes place in a universe that obeys physics much like our own. As of September 2016, we’ve done development on both the star system that Pavala exists in, and also the geography and geology of the surface of Pavala.
The Star SystemUnlike our own system, Pavala’s star system is composed of an orange dwarf called Yakei and a brown dwarf called Odius, separated by approximately 100 AU in a slightly eccentric binary orbit.
The Orange dwarf Yakei, a K1V class star, is approximately 5.1 billion years old. It has 9 or 11 planets, depending on whom you ask. The Yakei system is composed of three parts: The Inner System, the Transitory System and the Outer System.
The Inner System begins a mere two and a half million kilometers from Yakei, with the blisteringly hot planets of Tilekta and Enutu. These two planets are being boiled by Yakei, shedding large tails of gas that reach into the transitory system.
Tilekta is the hottest planet in the system at a nice and toasty 1900K, and
Enutu is the densest planet in the system, at a density more than twice that of Earth.
On the inner edge of the inner belt lies the gas giant
Siwa. Tidally locked to Yakei, it swings around the star in about 37 days. Siwa has the distinction of being the largest tidally locked body, as well as the smallest of the gas giants, at a mere 11 times the mass of earth.
The inner belt, held together by Siwa on the inside and Pavala on the outside, is composed of hundreds of asteroids and a large planetary object called Sokata.
Sokata is three fourths the mass of the Moon, and is also tidally locked to Yakei. While its day side roasts in the star’s heat, its night side is home to large deposits of ice.
Pavala orbits on the outer edge of the inner belt in a binary dance with the planet
Haki. Pavala and Haki are both habitable worlds, though humans originate on the planet Pavala. They are tidally locked to each other, and circle each other in around 24-26 (undecided) hours. Pavala has 92% the gravity of Earth, while Haki has 58% the gravity. The binary pair is circled by another moon, currently unnamed and around the size of Iapetus. There are some further captured asteroids in long period, eccentric and inclined orbits.
The transitory system is composed of three, large gas giants within a relatively cleanly swept region of space. The innermost gas giant,
Evonir, is slightly more massive than Jupiter. It has water-ice clouds, orbiting at the very outer edge of the habitable zone.
Vensada is the next gas giant, and it is slightly more massive than Saturn, and contains an equally diverse array of moons. The orange gas giant
Moke is actually more of an ice giant, with its low mass of 21 times that of Earth. It has two small, geysering water-ice moons and a third larger, captured moon.
The outer system has two planets and an icy kuiper belt. It’s everything that our outer system would have been, had Neptune not crashed through and thoroughly destroyed it. The sheer number of dwarf planets contained in this region would be enough to make anyone wish that Moke had migrated out further and crashed through it.
Rozava is the innermost planet of the outer system, a Titan-like planet in composition, yet an Earth-like planet in size.
Esteria is a planetary object on the inner edge of the icy belt, and it is more like the size and climate of Titan.
Many undiscovered and uncreated wonders lie beyond the eleven planetary bodies and two debris belts that I have just outlined, and they can be yours to create.
The planet of Pavala has two continents, code-named Pangaea and Continent #2. Pangaea is massive, around the same size as Afro-Eurasia, occupying an incredibly diverse range of climates. Continent #2 is smaller, but just as diverse, stretching from equator to pole, with rolling hills, flat plains and tall mountains. Civilization for the most part developed on the fringes of the pangaea.
Pavala has a day length roughly the same as Earth’s, but its year is only half as long, as Yakei is much dimmer and it must orbit much closer to it. From Pavala, one can see many of the other planets as incredibly bright points of light - some even during the day. One can see the moons of the gas giants Evonir and Vensada, and perhaps see some of the brightest asteroids in the inner belt.
Status update:So far, we’ve done most of the planets and moons, but lack some critical parts. We’ve also begun work on elevation, having finished a coastline map. This is taking longer than expected, but I will finish eventually.
I plan to eventually set up a wiki and many other web pages and resources when I get my website up and running, which will happen sometime this year.
