Derva, also known as Iena to the religious followers of Kehla, is a temperate E-Class planet found 1,297 light years away from Earth, roughly in the direction of the Orion constellation.

Also known as RS 8409-1353-8-10988376-574 4 in beta patch 7.

Discovered in 2338 by a young group of astronomers on Earth, it was believed to host a civilization with a similar technology to Humans. Later discovered to be the homeworld of an even younger civilization, having only existed for only 4000 years at the time. 

In 2193, the civilization, known as the Soara's, sent out an interstellar probe to search for other alien civilizations. At the same time, a series of messages were sent throughout the galaxy. Every message was the same; a simple "Hello" to other civilizations. Humans and other civilizations responded to the signals and, to the Soara's surprisement, many of them wanted to establish an alliance. Fortunately, it was agreed in the year 5026.

In 8027, Derva became part of The Intergalactic Confederacy, an organization that governs all civilized planets in the Universe. Derva was the third civilized planet to be part of the Confederacy. At its untimely demise, however, Derva appeared to fall alongside the Intergalactic Confederacy. Since then, it slowly recovered, and is a major colony in FUSS space.


Ranked as an Earth-like planet, it has an ESI of 0.895, an atmosphere with higher levels of oxygen and lower levels of nitrogen than Earth's atmosphere and an atmospheric pressure of about 90% of Earth's, a pressure that most humans can withstand. It has an age of about 12.7 billion years, about 900 million years younger the Universe itself. It has a mass 18% of Earth's and a diameter 58% of Earth's.

Cloud cover on Derva is a higher level than Earth's, reflecting more energy into space than Earth does in an entire year. The planet suffers harsh winters with a winter temperature of about -2.1 C, all across the planet. When the planet enters summer, temperatures can reach 12.4 C, almost the average Earth temperature of 15 C.

Derva's climate was being affected by the influence of the Soara civilization 6000 years ago (in the 3000's) which came to an end in the 5000's when new methods of collecting energy were installed across the planet.

Derva is now currently exiting an Ice Age, also known as the Interglacial Period. The ice from the recent Ice Age still remains in larger quanities at the south pole and with smaller amounts of ice at the north pole. The Ice Age, also known as the Aya Period to Kehla followers, began 30,000 years ago, long before the Soara's began their civilization. During this era of a frozen landscape, Soara's began to grow fur on their chests to keep them warm.

Life on Derva began about 11 billion years ago in small ponds of hot water which only supported tiny microbes capable of reproducing by binary fission, splitting into two every 1000 years. The lifespan of these microbes improved - from 10 years to 45 years within 2 million years - as the planet cooled down to more temperate temperatures to form the crust.

Plants began to cover the sea bed about 7.6 billion years ago. At this time, it is believed that a supercontinent - and the only continent at the time - formed with smaller islands surrounding it. In about a billion years, the first terrestrial plants appear on the supercontinent. The supercontinent split apart, taking the plants and trees with them across the planet. New continents formed and created the planet's surface as it is seen now.

Galactic Location

Derva is located within the Leyra solar system about 1,297 light years away. From Earth, it is found at: RA: 17h 30m, Dec: -20 degrees. These co-ordinates place it very close to the Orion Nebula, Barnard's Loop and the Witch Head Nebula. 

It is 391.4 light years from the Witch Head Nebula, 340.2 light years from the Orion Nebula, 482.1 light years from the Horsehead Nebula, 573.3 light years from M78 and 669.2 light years from Barnard's Loop.

Night Sky

Derva's night sky is dominated by Barnard's Loop, due to its proximity to the gigantic nebula. At the north and south poles are the aurora's, best seen at night. The brightest star, apart from Derva's sun, is Arneb, a white supergiant located 36.6 light years away from Derva. With the star's luminosity and distance to Derva, it becomes a -5 magnitude star, the brightest in the night sky and the easiest star to observe.
