"This Oceanic World, and endless sea of knowledge and elegance, home to the Hayalon Family, one of the most refined and glorious of all the Aristocratic Families. You can't really get more aristocratic than them. This is their world, a center for medicine, pharmaceutical and naval construction, as well as elegant fashion and architecture. It is also home of the delicious Takke Fish and the Tair Soup." - Senator Maes Prim
Thetis is an Oceanic world, full of little green islands scattered all over the Planet. It is located in the Asfodar System, in the Lewis Galaxy, in Herschel Space. It is one of the most important planets of the Empire of Mankind and has traditionally been the home base of the Hayalon Family, one of the most famous and powerful of the Aristocratic Families. They are known for its loyalty to the Emperor and its dynasty.

The local climate varies greatly, with some areas having tropical weather to some areas having vas stormy and cloudy or rainy weather for most of the year. Usually depending on latitude.

It was the homeworld of Halmara, the Emperor's famous mistress, and home to the Emperor Roldar I and Empress Larissa, both descendants of Emperor Teragan I and Halmara. The current ruling dynasty of the Empire, the Tarnos Dynasty, can trace their ancestry back to this family, since they have intermarried in several occasions. Halmara and his father Gildorn Hayalon, died in this planet after a rebellion of Human-born slaves revolted and took on arms against the Hayalon Family, taking control of the Hayalons home palace and the seats of government, killing who ever they could find belonging to the aristocratic families. Still Emperor Teragan I, out of sadness and grief for his lover, Halmara, severely punished the slaves that participated actively in the revolt, the assault and the killings of the Hayalons, ordering torture and death for about 70 000 slaves. Also the slaves families were executed.

Fortunately, some of the Hayalon family members were not in the planet at the time, leading later to The War of the Two Emperors. Roldar, Archduke of Thetis, noble bastard, claimed the throne and was crowned as Roldar I, making Thetis the provisional capital of the Empire, and served as such for the planets that pledge alliange to Roldar. Elpida kept being the Capital of Teragan I official son and successor, Kador V.

Thetis suffered and Assault from Loyal forces that end up in the destruction of most of Roldar's fleet and the death of Roldar in the battlefield. Larissa, was crown Empress II and kept the war with major success... although a standby point was achieved with neither band gaining mayor processes. So finally, Larissa II married its rival, Kador V, ending the war. They both ruled helding the titles of Emperor and Empress. When Kador V died, Larissa kept the rule until she gave it to its son.

The Planet was kept being a possession of Larissa II, as she was also the Archduchess of Thetis. Later, the title was given to her minor daughter and so the line was kept, tying loyalty of the Hayalons to the Imperial Throne for centuries to come. They are among the aristocrats with the highest claims to the throne, on the unlikely event the Tarnos Dynasty disappears.


The planet was colonized by settlers from Pax, Mitra and Elpida. Three vessels were sent from Pax, two from Elpida and two from Mitra with about 500k to 350k people each at first.

Later on the colony flourished and started spreading towards other areas of the planet, developing an intense oceanic drive and Naval spirit.

Colonist from Thetis were later sent to found planet Alma. Under the Republic of Anthropos a huge expansion and colonization program began, being Thetis one of the first colonies founded outside the 3 core planets alongside Haldar and many others.

The biggest city, Aisa, was founded by Elpidans, the second biggest city, Egana by Mitrans and Tiro by Paxians. Tiro was the largest city in the Planet until Aisa and Egana surpassed it in importance and population in the following milenia. Still Tiro keeps being the third most important city, and is the main financial city of thetis, holding ties to its old metropolis, Pax, and as them, they are consider highly rational and profit driven people. To keep tensions away from the three cities, the capital of the planet is located in Farsok. The Hayalon family though, lives on the Hayalon Island, a private Island that holds their residencial Palace. The Island is quite close to the Island where Farsok is located, so that most of the bureaucracy lives in that city and the Archduke or Archduchess travels to Farsok in case its needed or the bureaucrats and council members can go to the Hayalon residence to attend planetary issues.

Most of the Fauna and Flora in the Planet is made of Oceanic creatures, since most of the Planet's ecosystem is aquatic. However some large fauna can be found deep into the Islands of Thetis, with some of them even being used for food and other uses.

Some of the Native Species include the Apex Predators known as Teyak and Pandrian, both very related. The Alimoy is a predator on the seas and skies of Thetis and Hurden is an Inland predator, that lives in the Largest Island-continent of the Planet.The Shilduin and the Kozarban are large herbivores, usually both a targeted prey of all this apex predators.

The Alimoy is a flying creature, similar to a Birds like animal, that hunts mostly at sea, but goes inland for reproduction and refuge. This creature preys mostly on Take Fishes, the most abundant sort of fishes in the oceans of Thetis.

The Teyak is the Symbol of House Hayalon and has since then, being imported to other terraformed planets of the Empire of Mankind.
