The Great Continents of Corinth and Edeyn:
Corinth is a massive landmass that is home to many unique lifeforms. This great continent is home to various species of creatures and races. Races govern their own lands selfishly from one another but trading is fairly common between the three planes.
Corinth is bound by laws of nature that affect the land the same time and the same manner. A cycle of four seasons is used to measure the passage of time. Day is determined by the rise and set of the sun while the same goes for the moon. Across the three planes, all of its inhabitants share a similar fable in that a higher being created them in their image. Scholars across Corinth hypothesize that this is likely why all sentient life looks humanoid.
The floating paradise of Edeyn lies above Corinth in the sky plane which stretches above the land and sea and they are also subjected by the natural laws that affect Corinth. Its landmark is a series of highly elevated mountains that is surrounded at all times by endless clouds. A massive gateway somewhere within the mountains acts as a bridge between the two land masses. Land is kept afloat above the clouds through arcane means. It is the home of winged beings called Sylt'ar who built great floating cities and forts by bounding arcane power. While they still call the mountains their home, many of them migrated to Edeyn. Most of the wildlife are domesticated. Much of the scarce land in the plane of sky have been used as living space for the Sylt'ar. It is said that the plane of the skies is the most beautiful of the three planes. Streams of energy flow through the planes of the sky.
Corinth has many diverse geographical features, ranging from the vast plains to the scorching desert to the great forests. Many different types of species are found across the lands. In addition, the plane of the land is divided into major races. They are the Humans, Beastmen, and Krynar. They guard their borders zealously and rarely do they interact with each other except for merchants who travel on trade routes. News rarely travel fast. Although there are occasional skirmishes for territory, the leaders of each nations learn to coexist with one another. Rare creatures like giants tend to keep to themselves in remote areas of the continent. A great sea surrounds the continent and though the races of Corinth do not like to travel by water, ports do exist for the purpose of commerce.
The Empyrean Relics are said to contain the powers of the planes themselves. They are powerful artifacts believed to have existed since time's beginning. There are two relics and each one is present in a plane. The relics change their forms depending on their surroundings with respect to their planes. Although their power is immeasurable, it is drawn from the determination and strength of the users. In the wrong hands, these relics can cause misfortune. As such, they are used only in times of great emergencies.
Each race in possession of the relics uses them differently. Presently, the Sylt'ar is in possession of a relic that takes the form of a scepter. It is a symbol of leadership that is passed down to a new line of succession to prove their right to rule. The relic of the land was split into four pieces after events that occurred long ago. Each race in the land of the planes has a shard of the relic. The Beastmen's shard takes the form of an amulet while the shard of the Krynar takes the form of a ring. Considered to be their most prized possessions, these shards are locked away safely by both nations. As for the humans, the shard is that of a sword who chooses its wielder randomly. The last shard is lost to the ages, waiting to be found once more.
The Sylt'ar are winged human beings whose strengths lies in their speed and agility. They perceived themselves as the direct descendants of the gods. As a result, they believe themselves to be better than the other races. This attitude give them little reason to interact with “lesser races” and it is rare to see one in the planes of the land. They have a central governing body lead by nobles from various city states.
Sylt'ar looks exactly like a human but their white wings are the only thing that makes the difference. Due to their wings, the average Sylt'ar is physically weaker than a human. However, their military is formidable. Well trained in the uses of ranged combat and spears, they are a deadly agile and strong force to reckon with. In addition, they have a natural affinity for magic. Thanks to a period of peace and prosperity, the Sylt'ar's military is being scaled back but a well trained sizable army is still trained nonetheless.
On average, they mature around 10 and live to 40 years old. In death, they will become join with the energy stream in the sky plane. However, if they die and bear a burden, they are able to manifest as spirits and communicate with the living. With a stronger mind, they can physically interact with the real world. When they find peace, they will eventually join up with the energy stream.
Humans are among the most resourceful and ambitious among all the races. Years of wars with one another has kept the human race strong and steadfast. On the technological front, they are among the most advanced with airships and cannons.
Adhering to a class system, humans place great emphasis on birthplace and nobility. Classism is quite common and accepted. It is legislated at times. Those who find the means to learn topics such as engineering and magic often show an astute ability to learn, practice and advance into new frontiers. They are also among the must industrialized and their trade routes are quite comprehensive. City-states everywhere experienced a population boom when the late ruler united all the lands of humanity under one banner.
The former kingdom of humanity prospered but during it collapse, numerous warlords rose to take advantage of the chaos in their quest of power, splitting the area into numerous fractions. Only recently the lands were reunited.
Humans are the jack of trades in terms of their attributes. Calvary supported with infantry present a challenge to any foe. Organized warfare is favored but tactics used by the Beastmen are proving to be troublesome with this philosophy.
Many believe that the beastmen are savages who live deep in the forest homes. This belief kept most humans from ever venturing into their lands. While they are seen as primitive, it is far from the truth as they are civilized. Traditionalists by nature, they have lived and prospered far longer than any other race. Due to territorial expansion by other races onto their lands, Beastmen have a particularly strong hatred for them especially humans.
The Beastmen through some means are highly evolved than their lesser brethren. They developed a written and verbal language. Social with one another, they have knowledge of tool making. They are capable of standing upright and utilizing their animal instincts. Beastmen can be found in all forms from deers to the more predatory lions.
Matriarchal, all subsequent rulers were queens who ruled under a single house without interruption. Although they are fierce and impulsive individually, they are lost as a race without someone to guide them. While some evolved to Beastmen, many did not. These lesser beasts cooperate with their more evolved counterparts out of mutual bonds even though they cannot communicate with each other efficiently. Militarily, they use hit and run tactics especially in their forest home. Magical prowess is rare among Beastmen.
Powerful mystics whose powers are concentrated in the west, the Krynar look similar to humans but they become scaly and greener in appearance as they mature. An ancient gate separates the nation from the human and beastmen. Some say they came from dragons of old but many dismiss it as nonsense.
Both genders have an affinity for magic but females are generally more powerful than males. Magical powers physically change the beholder and auras can be seen by the most powerful Krynar. They live exceptionally long lives and they age very slowly.
They are prideful and independent folks and choose to spend their lives in solitude, traveling and thinking about intangible things. The Krynar are not as great in numbers as the other races. However, there are artisan builders and crafters, the best and efficient in Corinth. As such, their cities are large, magnificent and well defended. Their standing army is nothing to sneeze at either. War beasts, magical users and a powerful array of infantry ensures they are a potent force.
Their council is very conservative and they take a long time to make decisions, preferring to plan first before acting.
These are animals generally influenced by magic and they differ from normal wildlife in that they may have an innate control of magic they are born with and as a rule, they are much more intelligent than normal wildlife. Whether they are respected or hunted out of food or sport, their number dwindle as the years pass. Some arcane animals are gryphon and basilisks.
Through dark magic, the spirit of the dead can be brought back to the realm of the living. How they are seen depends greatly on the potency of the spell and the skill of the caster. They are rarely seen, let alone studied as all the races outlawed the summoning of celestials and the amount of power to summon one is massive. They are malevolent entities in all cases.
