House Obsianna has ruled Obsidsinoir since its formation centuries ago. Unlike neighboring nations who focused on building fortifications and strongholds, House Obsianna’s focus was on the future. Their focus was on aggressive infrastructure development, and technological innovation. Nowhere was this more evident than in the development of SERENITY. A massive airship, several kilometres in length, it took decades to finish, and completed its first flight without incident. An engineering marvel, it is seen by many as the most notable symbol of their ruling house, House Obsianna.
SERENITY is made up of 2 sections. The haie*-contained upper section is where the piloting, navigation and engineering sections all are. There are several levels under the upper section containing the haie. These include meeting rooms, weaponry and supplies, as well as quarters and eateries. The lower section of SERENITY is held up by specially-reinforced cables possessing a tensile strength said to be unbreakable.
The lower section is called “Home One”. It is several levels high, and runs from end to end. Marble floors, polished wooden walls decorated with gold and copper trim, crystal chandeliers adorning high ceilings make this ship's interior more luxurious and opulent than the royal castles of some rival nations. There are multiple facilities meant to occupy the passengers' time during long journeys. It has several quarters for the royal family and their guests. It is essentially a city in the sky.
A city with a view. A large slab of concave glass covers almost the entirety of the bottom of the lower section. Being able to walk freely on the tempered glass can make one feel as though they were walking on air. It offers a spectacular view, both at day or night. Interestingly , it is said the Sovereign's favourite time to take in the view is neither day nor night, but rather, dawn and dusk. Those moments just before the suns begin to rise, and the moments when they have just disappeared over the horizon. When asked by one of her young Wards why, the Sovereign replied that she enjoyed seeing the lands being washed over with light by the rising suns, or in watching it be blanketed in night as those same suns set.
A museum is housed within the centre of the vessel. This museum tells the history of Obsidsinoir and House Obsianna’s role throughout its history (from House Obsianna’s uncontested point of view). It is said to be so large, that it could not be confined to one floor, and has multiple levels.
It also contains a large floor map which details the location and topography of all known lands south of the Halvian Sea. They use this room for many of their meetings. To dignitaries of foreign nations, these maps help when discussing logistical and trade issues. The map also serves another purpose; to subtly remind the visiting delegates just how much knowledge House Obsianna possesses on each of their lands.
There are massive omni windows at the front, sides, back, and even bottom of the ship. The glass windows cover multiple floors and can be several meters long. This allows for a great amount of natural lighting. The glass alloy itself is tempered, able to withstand the harshest of elements and most known projectile weapons.
Several Soldat Rejal are on this ship. They are the personal royal guard of the Royal Family. One of the most decorated Soldats, Kinn, frequently occupies the ship as an escort to Heisun Obsianna, the future Heiress to the nation.
Heisun takes the SERENITY on its maiden flight across the Halvian Sea. Kinn accompanies her as a personal assistant and bodyguard.
*Haie is a naturally occurring gas that comes mainly from mining underground gas pockets. Said to be several times lighter than air, this element is known to exist only in the southern realm, with the largest reserves being in Obsidsinoir. While deposits of this element can be found in other nations, the reserves are much smaller, and their people do not appear to possess the ability or the means to refine it for use.
