Divinity War Worlds: Atlantis
An undeniably noble race, Atlanteans represent the best of what is considered human. Having come through their own doomsday and survived, this race possesses an innate wisdom, although their temperament remains as tumultuous as the sea. One never knows what answer they will get from an Atlantean.
Because the Atlanteans live underwater, their communication is largely sign language or written words inscribed on gold foil. These methods naturally lead Atlanteans to brevity in writing, while being more animated in personal conversations.
In order to survive underwater, the Atlanteans have developed an interdependent relationship with bubble kelp, which allows them to breathe beneath the oceans. This relationship and their past experiences have left them intensely environmentally conscious.
Unlike Earth's depictions of merpeople, Atlanteans are similar in appearance to aquatic mammals. A layer of dense seal-like fur covers the Atlanteans’ arms and lower halves. Their legs and hands are webbed, though they can hobble awkwardly on land with their wide, elongated flipper-like feet.
The Story of Atlantis:
Catastrophic climate change has left the surface of the planet Atlantis underwater, forever. As the Atlanteans’ grasp of electricity and magnetism reached the level of mid-twentieth century Earth, their use of carbon-based resources created a runaway global warming event. Surrounded by a tide of rising water, Atlanteans built increasingly larger and taller structures. After hundreds of years battling rising water, they resorted to genetic engineering.
Atlanteans are air-breathing mammals. However, their genetic alterations allow them survive in the shallow seas that were once home to their grand civilization. Bubble kelp generates enough oxygen at night to keep a sleeping Atlantean breathing until morning. Bubble kelp absorbs solar energy in the day and then it harvests carbon dioxide from an Atlantean's breath to complete the photosynthetic process. The unique co-adaptation makes the species interdependent for survival. Atlanteans will pipe air into underground rooms for tasks such as forge work. Otherwise, they keep to the water.
Their role in the gathering of the twelve worlds and in particular in the finding of Zion at the Prime Star is still unknown.
