Thiaseuris-Ulgan Jeppj (/θiːəˈsuː.rɪs ʊl.ɡɑːn ˈdʒɛp/) (occasionally shortened by locals to "Thiaseuris") is the second planet in the Toseike System, found within known Korvax space. It is a snowball world, currently locked deep into a global ice age, which few sapients have any interest in. It is known as the homeworld of the vegetation known as Karuts.


Thiaseuris Orbit

Thiaseuris from a distance

Thiaseuris-Ulgan Jeppj is a moonless planet in the Toseike System. It has been locked in a glaciation for tens of thousands of years, though it was once volcanically active with at least two known massive volcanoes, the supervolcano Mt. Vartarc and Mt. Mimmata, arguably the tallest peak on the planet, being the two most notable ones. It is a cold world with an average morning temperature of just past -40°F. That vegetation that can be found here are hardy, and large herds of herbivores dig for them, rooting through the top layer of snow that can sometimes be feet deep. Sapients must be careful of the numerous predators that predate upon these herds and thus can also be found in large numbers.

It has a mean temperature of around -42.6°F (-41.4°C) at night, with little to no fluctuation between the day and night cycle. Sometimes on less harsh nights however the temperature has been known to drop down to a practically balmy -21.4°F (-29.6°C).

Vegetation have figured out how to properly deal with the radiation and thus are abundant across the globe. The best example of this is the karuts, of which the planet is known for. Although fauna is technically only found occasionally, they live in large herds and so finding one means there are likely many others nearby. The predators tend to move with these herds. Aerial organisms are also fairly commonplace.


The Great DyingEdit

Although the exact nature of this event is unknown, it is known that the planet went through a massive extinction event that wiped out nearly all species on the planet and led to the collection of large amounts of detritum in the process. Studies have shown that this event coincided with a mass extinction event on the nearby planet Litvaardpa Dummi, which has left scientists to consider the event responsible as being a possible gamma ray burst from outside the planetary system, which may have hit at least these two planets in conjunction with one another.

Volcanic EraEdit

Thiaseuris 10

Mt. Vartarc, the now-dormant supervolcano

The volcanic era was the most geologically active period of history for Thiaseuris. During this time, eruptions were commonplace and many minerals were created during this time, including but not limited to Hoboroite, Komistoite, Musanbraite, and Ugheiite. It was during this time that the supervolcano, Mt. Vartarc, was last known to have gone off, leading to yet another planetary extinction event.

Genetic TransferenceEdit

Evidence has been recently uncovered that hints that the Gek First Spawn used enslaved Korvax to take life from nearby worlds and seed them across each other. Whether or not this had to do with the mass extinction events that had occurred or if it was a sheer display of dominance over planetary life is unknown. In the case of Thiaseuris, ancestral forms of several species were moved to and from here:

When Asalog led the successful Korvax rebellion in the planetary system, the First Spawn were driven out and the Korvax abandoned the planet to reside instead on Litvaardpa Dummi.

Common Eastea
(Eastea mendea)
Dark brown stalk, pale blue glowing bulbSomarinoaCommon EasteaCommon Eastea is a species of marrow bulb which feed via "external maintenance". This consists of using its psychotropic leaves to cause herbivores to get high off it, hallucinating for sometimes hours at a time. They will often vomit and/or defecate during this period, leaving nutrients for the Eastea to thus consume. They hold themselves in place via extendable roots which extend during storms to prevent them from getting uprooted. When they bulb, they are hard to differentiate from Common Jettum.
Common Jettum
(Jettum eirae)
Dark brown stalk, pale blue glowing bulbSomarinoaCommon JettumCommon Jettum is a species of marrow bulb which feed via regular photosynthesis. They live in interconnected "forests" which, despite being different individuals have roots that connect between one another and should on die, those surrounding it will take over the roots of the deceased and use as their own. They are vigorous by nature. It is hard to differentiate from Common Eastea at a glance.
(Undrioe delea)
Blue with deep blue berriesSomarinoaGemberyA species evolved from Platinum Berry stock. They support themselves with a many-limbed root structure and feed via regular photosynthesis. They are an altitude-tolerant species and thus can be found on the planet's tall mountains.
Network Cememica
(Cememica hadagiumea)
White tuber with green leavesSomarinoaNetwork CememicaA species of Diekon which subsists on free radicals in the substrate. They have a substantial root system, hence their name. They are a useful herb, and is pharmacologically active, acting as a powerful pain reliever when harvested.
Plunging Argelica
(Argelica fofodiutioneus)
White tuber with curled green leavesSomarinoaPlunging ArgelicaA species of Diekon which recycles soil and feeds upon the nutrients found within. They have an "unfathomable" root structure, which drops hundreds of meters below the surface. They reproduce via moldy bulbs. It is visually difficult to differentiate from Snowball Fontae.
Snowball Fontae
(Fontae rotondoumeum)
White tuber with curled green leavesSomarinoaSnowball FontaeA species of Diekon which subsists via "meditation", making it one of the only known "breatharian plants". Their leaves are parasitic, and small needles will stab and absorb the energy from passing organisms. The structure of their leaves often collect snow, creating a natural snowball. It is visually difficult to differentiate from Plunging Argelica.
Sunbathing Angervine
(Ourbii egypitae)
Pale blue with vibrant green and pale blue leavesSomarinoaSunbathing AngervineA species of Angervine. They utilize an independent root structure, giving them a more worm-like appearance as opposed to most other known Angervines in the galaxy. They feed on ultraviolet radiation which they use to help produce luminous bulbs by which they reproduce. Like Litvaangervines, they can often be found feeding on the planet's Palateworms as well.
Thiaseuris Snow Intestine
(Prumeus nacoreus)
RedSomarinoaThiaseuris Snow IntestineA species of Snow Intestine that was brought over and evolved from the Snow Intestines of Zukabergo-Nama Gusuk. They have a significant root structure and feed by using microorganisms for anaerobic digestion. Their pods convert over time into sacs that produce powerful pheromones, which then later become Thamium9-laden seeds.

Beavrat Female

The most common species on the planet, these small, grazing creatures live in small families. They are normally passive, but become territorial when they nest within Aylevite during breeding season. They are primarily herbivores but will supplement their diet with the occasional Heatwing. Males have curved horns while females do not.
Headlatched Weggasaur

Headlatched Weggasaur

Headlatched Weggasaur Female

A Weggasaur that has fallen victim to the Headlatcher parasite. They remain meat-eating hunters by nature, but now seek to help the Headlatcher to reproduce. The underlying Weggasaur is technically dead and is permanently in a zombified state, with the majority of its head removed and only the brain and spinal column remaining.
UnspecifiedUnspecifiedSomarinoaNo ImageA legless parasite that normally live on the upper reaches of caverns. Although they are almost pointlessly slow, they sneak up on Weggasaurs that rest in the caves and drop onto them to replace their heads and control their bodies, allowing them to move between caverns to spread their genetic material over a wider area.
(Cobaneumae dotumb)
0.61m41.37 kgSomarinoaHeatwingLarge insectoids that flutter close to the ground. Although they are occasionally a supplemental food source for Beavrats, they are more often than not gathered around by the herding species. This is because their large wings course with blood vessels and are seering to the touch, which is both a defense and survival tactic. They subsist on oxide elements.
(Pihloepheae shumi)

Pihlogaster Male


A species of carnivorous scavenger usually found inhabiting crevasses in the ice. While they normally will feed upon unfortunate creatures that fall into the crevasses, they will not shy away from an organism that appears easy to take down, such as Beavrats. Their genders are outwardly identical.
(Kampisae besa)

Skoff Male


A species that exist in vast herds covering large swathes of the planet. They are so named for their appearance, which looks like they've turned their nose up at others. They subsist on oxide elements found in the vegetation and will even lick minerals to get what they need. Because they are so often predated upon, they have a defensive nature. Their genders are hard to tell apart simply by viewing them.
Snowshoe Gekdog
UnspecifiedUnspecifiedSomarinoaSnowshoe GekdogA species evolved from an unknown genetic ancestor from Zukabergo-Nama Gusuk. They nest in caverns and crevasses across the surface, but must travel to forage for food. They have adapted large toes and feet to displace their weight and let them run freely on top of the snow.
(Jeanciaea xulti)

Thiasaurus Male

Thiasaurus Female

The apex predator of the planet, the volatile Thiasauruses are found in surprising numbers across the planet, chasing down and feeding upon the many large herds of herbivores. Despite this, they more often than not scavenge their meals similar to a Tyrannosaurus rex. They show extreme sexual dimorphism.
Thiaseuris Euphrotha
(Irmisicae oporar)
Male: 1.44m
Female: 1.3m
Male: 87.67 kg
Female: 83.77kg

Thiaseuris Euphrotha Male

Thiaseuris Euphrotha Female

A species of amenable herbivores. They, like many other species on the planet, exhibit sexual dimorphism. Males are larger, with anvil-headed and possess the slated back of many of their brethren to hold their young, while females have large sails and tusked, snouted faces. Females are blind and rely on their powerful sense of smell, and will follow around males for their own safety.
Thiaseuris Palateworm
(Ifloe kuviorica)
UnspecifiedUnspecifiedSomarinoaThiaseurus PalatewormA species of Palateworm. They hold themselves in place via efficient lobes to form a makeshift root structure. Because of the cold of the planet, they keep themselves alive by keeping in close proximity of geological energy, which they also use to sustain themselves. They are often jokingly referred to as having an "inner beauty".
Thiaseuris Slateskull
(Yimnoea hayn)
0.97m62.55 kgSomarinoa

Thiaseuris Slateskull Male

Thiaseuris Slateskull Female

A docile species evolved from Slateskulls brought over from Zukabergo-Nama Gusuk. They are grazers, and are often found intermingling with the Skoffs and Beavrats. Males have the slate-like skull structures that are used for sexual displays, and females develop the slated backs to carry their larvae. They have gained stiffened tails to allow for swifter, more agile movement to escape the planet's numerous active predators.
(Wayompnustreusera aruss)
0.95m58.44 kgSomarinoaToucacarkA species of large aerial organisms with a distinctive, almost playful personality. They live in small flocks and subsist on absorbed nutrients. Their genders cannot be determined without in-depth study.
(Mecomiflocimae wegga)
1.91m113.89 kgSomarinoaNo ImageA species of predator closely related to the larger Thiasaurus. They must feed on the same creatures and often do the killing that Thiasaurs will steal if given the opportunity. They are parasitized by the Headlatcher.

KorvaxAverageUnspecifiedFirst SpawnKorvaxThe Korvax are inorganic lifeforms that inhabit metallic casings passed down from generation to generation. They believe that through mathematical study they can be raised to the level of the Atlas, and that the path to this is through the study of the Sentinels.

Each Korvax is a pure mind, a drop in their great collective Convergence. The shell they inhabit is of little significance compared to their connection to this group consciousness.

The Korvax were enslaved by the Gek First Spawn, and many still view the Gek with deep suspicion.
