Divinity War Worlds: Tesser
Tesser is the 11th of the creator's twelve worlds and closest to Earth. Pale skinned, with large eyes, fragile builds and "alien"-like oval heads, Tesserians are everything humans expected to find in space--but we were too late. Using ancient religious texts from three other inhabited planets as guides, Believers first charted the location of the planet Tesser and arrived to find its great cities vacant.
The characteristics of Tesserians are not entirely known, but their records indicate a deep sense of caring and respect for others, a love of order and peace, empathy, compassion, patience, and a need for being connected with others.
The communal Tesserians were the first to achieve interstellar travel. But the planet harbors a strong magnetosphere that prevents stellar radiation from creating a large supply of Tritium for fusion, and an energy crisis brought the harmonious Tesserian civilization to the brink of collapse. Seeking access to Earth's massive supplies of fossil fuels, oceans rich with Tritium and a crust rich in heavy fissile metals, Tesser launched a desperate mission to reach humans who were just taking their first steps into space. After a secretive first contact, a large supply of US-made Plutonium was sent back with the Tesserian ship. But the gift came with a price. An outbreak of Earth-borne viruses on Tesser brought the peaceful civilization to a grim end. The planet's spectacular cities and skylines are but gravestones.
Rumors that primitive Tesserians had survived in the wilds of the planet were not enough to convince any of ASP's affiliated commercial enterprises to send trade ships to the out-of-the-way planet with few natural resources. Relics of Tesser technology have been found in Believer space systems. However the full extent to which Believers benefited from Tesser technology is not known as the Believer fleet avoided a full scale conflict with ASP at Avalon following the extermination order, and instead fled to Xahna.
