Terra
Terra is the third planet in the Sol system. It is home to a large diverse ecosystem of organic creatures, the dominant species being humanity and their esper offshoots. Following the crash landing of the Ark and Nemesis in Terra's prehistoric era, this planet has become a focal point of contention between the Autobots and Decepticons since their reawakening.
Terra is a spheroid-shaped terrestrial planet with a diameter of 10026 km, an orbital speed of 101,326 km/h and an axial tilt of 26.3 degrees. Formed roughly 5 billion years ago along with the rest of the solar systems, Terra is the only planet in the system that can naturally support life, with two-thirds of the planet consisting of water and the remaining percentage being physical landmasses. Terra's only natural satellite is its moon; Luna.
Terra has seven continents, each of which are divided into various countries. These seven continents are Delpoi, Azteca, Europa, Usea, Libya, Nyx and Antartica. These seven landmasses are separated by seven bodies of water; the Deldaros ocean, Florecio ocean, Zerros ocean, Andar sea, Daras ocean, Sheed ocean, and the Akua sea. Aside from continents there are also a number of smaller islands dotting the world's oceans, inhabited to varying degrees.
Terra is a world rich in natural resources, which would make it a primary target for Decepticon invasion. Its most abundant resource is hephaestium. Discovered in ancient times, hephaestium is a natural energy propellant that burns hotter than coal and is triggered by the exposure of energy to its prismatic composition. It serves as a power source for over half the technology on Terra, from airships to Talos, though other energy sources are also employed. It is found in its raw crystalline form and can be processed into a fine powdered form distributed commercially. The downside to hephaestium is that it is highly combustible in both forms if violently handled in high temperatures.
Continents
Delpoi- A continent entirely within the northern hemisphere and almost all within the western hemisphere. It is the third largest continent by area, following Usea and Libya, and fourth in population after Usea, Libya and Europa. It embraces a very climatic zone. Subartic and tundra climates prevail in north Canadia and north Alaska, and desert and semiarid conditions are found in internal regions cut off by high mountains from rain-bearing westerly winds. However most of the continent has temperate climates very favorably to settlements and agriculture. Prairies or vast grasslands cover a huge amount in mountain is home to the Helic Republic, a democratic country composed of 50 states, each governed by a senator and the affairs of state are overseen by the President of the executive branch of government.
Azteca- A continent also in the western hemisphere, mostly in the southern hemisphere. It ranks fourth in area (after Usea, Libya and Delpoi) and fifth in population (after Usea, Libya, Europa and Delpoi). Azteca is located near the equator, which owes its abundance of flora and fauna. Its climate is in the 70s-high 90s all year round and 90% of its land is covered in rainforests, which hold 30% of the world's animal population. Azteca has several sovereign states that form the Aztek Federation with its own military force.
Europa- A continent that comprises the westernmost part of Emmeria, the combined continental landmass of Europa and Usea. Land relief in Europa show great variation within relatively small areas. The southern regions are mountainous, while moving north the terrain descends from the high Alps through hilly uplands into broad, low northern plains which are vast in the east. An arc of uplands also exist along the northwestern seaboard. Politically, Europa is divided into about fifty sovereign nations of which Arcadia and Dalmasca are the largest and most populous. Most of these countries, including the Britannia Empire (which is separated from Europa) are a part of the European Union, a coalition of nations in western Europa.
Usea- The world's largest and most populous continent, located primarily in the eastern and northern hemispheres and shaping the continental landmass of Emmeria with the continent of Europa. The continent, which has long been the home to the majority of the human population, was the site of many of the first civilizations. Usea has extremely diverse climates and geographic features. Climates range from artic to subartic in Sato to tropical in southern Sapin and southeast Usea. It is humid across southeast sections and dry across the interior. The monsoon circulator dominates across southern and eastern sections due to the presence of the Himalayas drawing in moisture during the summer via thermal low. Usea is divided into 48 countries, two of them (Dalmasca and Brasnya) having part of their land in Europa. The largest countries in Usea are Xing, Sapin, Joesun and Yuktobania.
Libya- The world's second largest and second most populous continent. Libya is a rainy and dry place; because of its geographical situation, Libya is a hot continent as the solar radiation intensity is always high. Thus, warm and hot climates prevails all over Libya, but the northern part is mostly marked by aridity and high temperatures. South Libya has a transition to semi-tropical or temperate climates and more desert or semi-arid regions. Libya contains 54 fully recognized sovereign states, which are joined together in the nationwide Libyan Union.
Nyx- The smallest of the seven continents. Nyx is located in the southeastern hemisphere, near the equator. Nyx's climate is mostly arid, semi-arid or tropical. Much of the northern and central areas are covered in prairies, bordered by small mountain ranges and deep valleys full of large plants. Thanks to seasonly rainfalls, Nyx is a predominantly fertile land that is also known for having large amounts of hephaestium in underground cave systems that tunnel under most of Nyx's surface. In Nyx, nature rules. Due to some odd form of Darwanian evolution, much of Nyx's fauna were exclusive to that region of the world, and had evolved to become what many would call fantastical; Griffons, Hippogriffs, Dragons, Pegasi, even Hippocampi. Creatures that look more like amalgamations of pre-existing species than newly evolved creatures. Here, predators grow tremendously and possess powerful physical abilities strong enough to demolish tanks and Talos. It is their presence alone that deters humans from fully settling on Nyx.
Antartica- Terra's southern most continent. It contains the geographical south pole and is situated in the Antartic region of the southern hemisphere, almost entirely south of the Antartic circle, and is surrounded by the Southern Sea. As the fifth largest continent, Antartica is covered by ice that averages 1.9 km (s.2 miles, 6,200ft) in thickness. Antartica is the coldest, driest, and windiest continent, and has the highest elevation of all the continents. The continent has about 90% of the world's ice (and thereby about 70% of the world's fresh water). If all this ice were melted, sea levels would rise about 60m (200ft). There are about 135 permanent residents, but anywhere from 1,000 to 5,000 people reside throughout the year at research stations scattered across the continent. The rest of the population are native animals such as mites, nematodes, penguins, seals and tardigrades.
