Alterra Planet
Habitable planet in the system, and closest to Deltaspark. Officially it is called Δ-01. Alterra has a very rich and diverse, both in nature and cultural.
Favorable conditions for life and development are provided by a combination of many factors. For example, the small inclination of the planet’s rotation axis, its comfortable distance from the star, the abundance of water and mineral resources, geological diversity. A lush and diverse biota intricately mixed, forming many new natural phenomena and biological species, significantly transforming the entire planet.
Alterra's only satellite is the icy moon Esnem, made of melted water conventional ice and covered with snow. So, it looks like a pure, white and shining ball in the sky.
Planetology
Δ-01 is a rocky, earth-like planet composed of basalts with a metallic mantle and core. All kinds of ferrous, non-ferrous, platinum and lanthanide metals are found quite often in the form of various mixed minerals. The main difficulty is not to find, but to separate rocks into pure elements, although some natural "alloys" may be useful, but this is not suitable for precise dosage and industrial use. Overall, there is a great variety of different minerals on Alterra.
The planet's atmosphere is oxidizing, the most common gases (in order of decreasing proportion) are nitrogen, xenon and oxygen. There is also a lot of water vapor, which, in addition to the hydrosphere, also makes up several rather dense layers of clouds. Heavy xenon, despite settling in the seas and lowlands, is actively mixed by the wind, which ensures its more or less uniform distribution in the atmosphere. The sky of Alterra looks bluish-purple, and at dawn it turns into shades of pink.
Water, air and rocks...
The minimum axis tilt, proximity to the star, cloudiness, and abundance of internal water in land masses make the planet’s climate warm and humid. The climate depends on latitude; the closer to the poles, the colder it is. Temperature zones alternate from dry polar to humid equatorial. In altitudinal zones, the climate varies depending on the altitude — the higher you go, the colder and drier it is.
Δ-01 completes an orbit around Deltaspark in 384 days — 12 months of 32 days. A week consists of 8 days. The planet has dry and wet seasons; the transition in the southern hemisphere from dry to wet is marked as the beginning of a new year.
Population
Biological organisms on Δ-01 are organic-composed of hydrocarbons.
As elsewhere in Deltadim, all sentient characters share a common anthropomorphic profile, but can vary widely in appearance and internal structure. The main biological species are represented by felines, lagomorphs and canines. In addition, many characters combine characteristics of different species. There are many such characters with various cybernetic enhancements.
There are also unique "small" species such as Blobunnies — an unique biological species on the planet (on par with Blobcats), and Fibrins that also common on Alterra.
Among robot characters, anthropomorphic individuals are also common, having individual features of cats, rabbits, dogs, etc.
In general, developed transbiological technologies and cyborgization allow characters to completely control and change their body. So Nala, Moka, Eros at one time changed their gender without any problems. Articat successfully created a clone of Artibun based on his genetic material, with minor modifications.
Architecture
Architecture is a kind of complex and multifaceted reflection of culture and production relations, and of course the environment where it was formed and which it, in turn, changes.
Let's look at the main architectural styles.
Art Deco
Distributed throughout the planet, having implements the features of other styles, but mainly this style is concentrated in the south. Art Deco is characterized by a certain simplicity of forms and conciseness of volumetric structures, combined with a complex structure, clarity of division, rhythm and a combination of uniform and bright colors. This is a fast, laconic and at the same time complex style.
Rocaille
The peculiarity of this elegant style is light, airy, smooth and whimsical lines and shapes. Decorative elements involve stylization of fantasy forms of natural objects — rocks, shells, leaves and flowers. The color scheme is pastel, halftones and gradients are actively used. A characteristic feature of rocaille is the intricacy of structures, "fluidity" and asymmetry. There are almost no straight lines in it. The style is common in the central and eastern regions of Alterra.
Classicism
Based on the principles of order and symmetry. It is distinguished by simplicity of forms and constructions, strict proportions and restraint of decoration. Relatively simple decor fits neatly into designated small spaces, such as capitals near columns or coffers of ceilings. The colors are monochromatic composed and uniform, but muted, the number of shades is minimal. The classicism style is common in the north and northeast.
Constructivism
The basis of the style is simple geometric shapes, "raw" or, conversely, highly processed materials. A minimum of colors and shapes, a rejection of multiple accents in favor of a minimum, or no accent at all. Interestingly, despite that, this style is the most receptive to experimentation. Constructivism seeks to absorb and quietly adapt the unusual. He departs from the canons and does not pretend to do much. This modest style is most common in the western regions of Alterra.There are many transitional, quirky combinations of styles, especially at the "borders" of architectural "areas".
Urbanistics
In its full form, architecture represents itself in urban planning. Cities, like the architectural styles in which they are built, vary quite a lot, including in layout.
At Alterra, there is an established division of layouts into metropolises and suburbs.
The first are centralized, made according to a single plan, and, as a rule, very large, with a regular, geometrically verified shape, alternating with parks and other places. In metropolises, buildings are huge, multi-story and vertically oriented. They can include and combine apartments, offices, production facilities, transport hubs and various leisure facilities — clubs, theaters, internal parks, distribution shops, art galleries, etc. The buildings separate huge spaces of gardens and parks from each other, so that instead of a clutter, there is a sense of spaciousness and monumentality.The entire network of metropolises is composed of many highways — transport and pedestrian.
Suburb cities are a collection of enclaves neatly and smoothly integrated into the natural landscape and interspersed with it. Low-rise buildings with separate buildings with specific functions are typical. If the buildings are united according to any principle, for example, these are the parts of a research institute or an industrial enterprise, then they are collected into a single dedicated complex, usually including parks and other elements. Suburbia, as a rule, do not have clear boundaries. The development gradually becomes sparse, individual enclaves move away and become smaller... Until you begin to approach another similar city.
Alterra is divided into 20 regions and has 50 major cities. Region is a territory defined by the totality of natural and associated production and cultural features. Each region can have its own distinct style and be close to neighboring regions.

Planetography
The surface of the planet is represented by a group of connected subcontinents, many smaller islands and oceans washing it all.
Water and land are distributed unevenly across the hemispheres. Continental masses are grouped closer to one meridian and form a hemisphere of land, while the bulk of water occupies more of the opposite hemisphere.
As already noted, the continents are connected to each other and essentially form one large continent. However, due to natural differences, cultural characteristics, outstanding forms, and also for reasons of convenience, four continents are distinguished.
In the Lurconicum Ocean there are two islands — Muffin, which separates the Vollen Sea from it, and the southern Brubek, as well as the large Leyoun archipelago. In the Ebrium Ocean there is a small archipelago called Bikert. Despite the lack of large islands, Ebrium has two major underwater cities.

Lindev
The central, largest continent, the only one that connects the northern lands with the southern ones and is separated from them by mountain ranges. It is washed by two oceans and has two large inland bodies of water, one of which — Danau Putih — is connected to the Ebrium Ocean by a long and wide eastern strait, the other is the largest closed body of water, Basse. All this, combined with smaller lakes, makes the largest continent the mildest in climate. What affects nature? Large forest areas, sometimes very dense and varied, as well as gentle and hilly terrain are the distinctive features of Lindev. Most of the cities are located here and the main highways of the planet pass through.
Dowe
A rounded southern continent crowned by a small, rounded inland lake. Bounded by the southern mountain range and the junction of two oceans — Lurconicum and Ebrium. It has a little bit of everything — steppe, lush forest and several hills.
Flave
A mountainous continent composed of three largest folds, stretching from south to east. It is washed by the Blues Sea in the north, the Vollen Sea and the Lurconicum Ocean in the south. Here the altitudinal zonation and the associated diversity of biomes are most pronounced.
