Terra (Planet)
Terra is also the only place within the known universe where intelligent creature which people within the the universe usually just called mortals have the most amount of variant as different races and species within the planet of Terra life with one another, this maybe because of Terra very much safer environment from the past to even currently compare to the other realm that seem to have a larger amount of danger from several to many thing which is related to their biome with the extra of some of those planets having dangerous weather that may have causes life to suffer or have to adept to something that is very different from life that life in Terra which have the purpose of able to continue on living within the unfriendly environment, or animal/beast that within the planet of Terra is one more tame or friendly compare to any other realm which may hold beast that endanger the citizen of those realm, Terra huge variety of different races is also because of how Terra is the center of the cluster of known planet where other creature or races can travel to Terra as it seem Terra is also a pretty large planet that make it other realm can travel into Terra especially with the amount of mythical creature that the other realm have which may have their own ambition to travel to Terra.
Terra is the only planet that is within the the known universe where a bunch of creature that can be count that hold a lot of divine energy compare to other planets where there is only a few to one being that hold the trust and faith of the people of that planet where they can be count as a deity or a god of that realm which Terra seem to not have as different gods holding different domain rule over the lives of the people even people of Terra believe upon other worldly gods or goddess or being because it is related to what they believe upon, as it is rare sight to see a creature from a planet believing upon a being for their teaching and ability from another far away realm which is what some people within Terra is doing, even if the amount of people who are doing is to few is still something that in the known universe is rarely seen as creature trusting and putting faith onto multiverse gods and goddess, even the main god of Vallarian that unite the people together is the Six Stars of Fate which in tale that the believer of the Six Stars believe upon told that one of the group of the Six Stars is from Vallarian while some of those other group are from like Titanfall or other realm even so the people of Vallarian is the highest amount of percent of people believing onto the Six Stars of Fate compare to other realm or planets within the known universe.
Etymology
The origin of the planet name is very known thing for someone who are interested about this type of subject as the word of Terra come from the old word that folks from the continent of Titanfall which was the only major continent during that time as before the creation of Vallarian was the name Terra form and use by people to describe the entire world that they know other than Titanfall as some people have learn about the knowledge of other world from just seeing up in the sky especially back in the day before Terra Shattered Sky phenomena, where some stuff within the now a day sky compare to back than are very different to not a single change because of the strange illusion effect that is cause by that Terra Shattered Sky, even so people know about other world and also other places like the Lost Isles as it is the only place other than Titanfall that exist during that time.
As Terra was originated from the ancient Titanfall language of where it have a meaning of land or soil as it is suppose to describe the world what the people back then see, with the word of Terra spreading to other realm as well as visitor from other realm started to use the word Terra to describe the planet as the word it self does not really have any conflict with any other languages in the known universe at that time but also because how already wild spread it is for people in Terra it self to use to describe the world that they are living on, this eventually spread when the Vallarian continent was created with most of the mortals living at the start of the continent life being people who came with the Vallarian to life in the new place, which in that time period is already common for people to describe the planet that they are living in as Terra.
Environment
Land
The environment that exist in the planet of Terra are very different from one and another a especially the land which have different soil content and biology who lives in different section that may differ from one and another due to the distance that the planet of Terra have and also the extra different of the two main continents of Vallarian and Titanfall Isles where one is created by a bunch of demi-god and other one is naturally forming by the energy that is within Terra it self, that is usually called the Heart of Terra but before they become the creator of Vallarian, they were called Guardian like the other demi gods that exist within Titanfall, which later the Guardian that later become Vallarian created the contients that have a bunch of different biome and environments from grassland, rain forest, desert, canyon and many other type of environment which make different creature prefer living within that specific location due to their evolutionary ability that may cause them to have a higher chance to survive in that location, while the Lost Isles it self are a bunch small islands compare to the other contients major islands that they have around them, making the Lost Isles one of the smallest 'continent' within Terra compare to the other continent, even so the Lost Isles are located in a spot that allow travel between Vallarian and Titanfall due to being located in between Vallarian and Titanfall, where it's environment of the isle is more of the tropical, which is something that isn't exlusive for the Lost Isles as it exist in other regions within other contients.
Water
The water within the planet of Terra are mostly what comprise the planet with the landmass of the planet only being around 20-30% of the planet surface while the Terranian seas it self hold the other 70-80% of the planet surface this of course make the distance between the contents of Vallarian and Titanfall very far apart from each other where the Lost Isles is located around the middle section of where both continents would be, making back in the day people of Titanfall and Vallarian not even able to contact each other without any magical mean, which even now a day is impossible to do with normal ships due to the length of the two continents from each other that will take more than a most creatures years of living in the sea it self to travel from each other.
The body of water that separated the continents from each other within the realm of Terra have one name to be called The Great Leviathan Sea even so such as the name implies for those who knows the legend or even have survive an meeting with one across the sea, the sea it is inhabited with leviathan that exist within the deepest of the sea, while if a ship only travel across along Vallarian, Titanfall or The Lost Isles they will not meet such creature but if they were to travel to the deep dark sea of The Great Leviathan Sea, a chance to meet them during the long travel between continents is risen to around 8% even so the biggest danger of travelling within the body of water is not the creature that exist within the depths it self or natural phenomena such as large waves that was recorded by those who sail such sea, but the travel distance between land that would take a ship sailing for 15-20 years to reach between Vallarian and Titanfall this make people within the ship needing high amount of supplies that they need to even survive the travel but also enough mental state to not go crazy between the travel of such legth of time within the sea.
