Aman Sinaya is as beautiful as it is magical. While the population is mostly Mers, all races can be found here, coexisting more-or-less peacefully. The city can be described as thriving and well-maintained, though also sprawling and eclectic. Aman is the centre of magic, religion, and education for any sea race member. It has a very low crime rate.

Aquatica was built by S.H.A.D.O.W. using technology discovered on Shadow Island. At first it was staffed by scientists from Australia and New Zealand but soon after they were approached by emissaries from Aman Sinaya and came to an agreement which would be mutually beneficial to the two cities. With the aid of engineers from Aman, Aquatica was greatly expanded with a portion set aside for undersea races. Today Aquatica has a true mix of above water and under water races.

In 500,000 BC the Harmonic landed on earth and established various refugee bases around the world for those fleeing from the tyranny of the Celestial Alliance. They were careful not to interfere with the native developing races of the world. Among these bases were Atlantis and Lemuria. Unbeknownst to them Atlantis was built on top of the largest ley line in the world. Around 100,000 BC Elves discovered Atlantis and were welcomed with open arms by the Harmonic. They begin retraining in the art of science as well as the more recent art of magic. In 80,030 BC a set of twins were born; Doomslayer and Dreamslayer. Both eventually become Battle Mages but Doomslayer choose to serve Order while Dreamslayer turned to Chaos. Later in 79,990 BC after the loss of the Atlantean Mage King during an invasion by demons, Doomslayer became king. One of his greatest foes were the Lizard Men, who use their shape changing abilities to resemble human beings and infiltrate human civilizations with the intent of conquering them. Doomslayer managed to uncover most of the Lizard Men's plots and had many of them killed. 

Just ten years later Lizard Men sorcerers discovered the Necronomicon, the ancient mystical tome penned by the Elder God Kali. Founding the first Cult of Kali, they began experimenting with the spells contained within, looking for a method to cause their enemies to return from the dead. They were successful in resurrecting them as the first vampires and unleashed them against their greatest enemy, Doomslayer of Atlantis. However Doomslayer proved more powerful than they realised and with Gaea's aid was able to destroy most of the undead. The surviving vampires fled to continental Eurasia. Doomslayer then hunted down and slew all of the Cult except for one. He fled and eventually settled in Eurasia, taking the Necronomicon with him. Over the next few millennia the tome passed through a number of different hands. 

Doomslayer eventually died in 79,920 BC from natural causes. With no apparent successor available a ruling council was elected instead, the first form of democracy. By 71,000 BC Atlantis had begun to slide into decadence and suffered from a number of invasions from the nation of Lizard Men as well as a rapidly cooling climate. Foreseeing that the approaching ice would eventually reach Atlantis, the ruling council had huge glass like domes erected over the city and fortified its foundations. 

70,000 BC saw the final invasion of Atlantis by the Lizard Men. To stop the onslaught, the council opened the magma pits which were the city's main means of heating. The Lizard invaders were all destroyed, but the magma release triggered a seismological cataclysm which caused a series of earthquakes throughout the continent. Atlantis sank into the ocean. In order to save their human allies the Harmonic bestowed various bodily attributes on them enabling them to live indefinitely beneath the sea. The Atlantean Harmonic then relocated to Lemuria.

Hundreds of years later, Atlantean scientists developed a serum that would mutate humanoids, giving them fish-tails instead of legs.

Location: North Atlantic Ocean, north of the Canary Islands near Africa

Depth: 200 metres

Races: Atlanteans

Technology: 7

Culture: Standard. Diversified mix of kind and evil people. The religion of most tribal Atlanteans is pantheistic nature-worship. The state religion of monarchistic Atlantis revere the Greek god of the sea Neptune, who once lived among the Atlanteans two millennia ago. The Atlantean Empire in many ways resemble the ancient Roman Empire at its zenith. Atlanteans subsist on raw fish and seaweed. They are largely a hunter/gatherer society, who have made successful attempts to farm seaweed. In the Atlantean capital, society is stratified so that there is a special guild of hunters and gatherers who provide food for the entire population.

Government: Military Council. The Atlantean government has traditionally been military, with a Council of Elders, who serve as the judiciary and legislative branch of government. Atlantis has a standing militia who perform police functions in times of peace. Although the monarchy of Atlantis claims all Homo Merrmani dwelling in the Atlantic Ocean as its subjects, in actuality the monarchy neither provides services or protection nor demands tribute or recognition from those who live beyond one day's swim from the capital city. Most Homo Mermani continue to live tribally.

Kitezh is a Kopru city, a bastion for most of the evil in the ocean. When you need an crime committed under water or black market or stolen goods, Kitezh is the place to go.

In 500,000 BC the Harmonic landed on earth and established various refugee bases around the world for those fleeing from the tyranny of the Celestial Alliance. They were careful not to interfere with the native developing races of the world. Among these bases were Atlantis and Lemuria. After Atlantis sank in 70,000 BC the Atlantean Harmonic relocated to Lemuria. Later in 8350 BC a Tsaurid empire battleship arrived on earth attacking all Harmonic bases including Lemuria. Lemuria destroyed the battleship but not before its orbital bombardment caused shockwaves worldwide. With whole continents being swamped by tsunamis, Lemuria, like Atlantis before it sank beneath the waves. The Harmonic in a panic over the amount of life being destroyed broke their own laws regarding experimentation and transformed some humans into water breathers. They were eventually able to reclaim Lemuria and Atlantis.
