#pendulum wars

A boulder of a man, Tai’s muscular appearance stands in contrast to his quiet, meditative personality. Tai was descended from a long line of men who viewed themselves not just as fighters but as warriors. This lineage molded Tai into a warrior-philosopher with a spiritual view of war that often caused odd glances from his squad mates, however, they liked and respected him, even if they didn’t always understand him.

Decades before the Pendulum Wars, Sera was plunged in the millennia long conflict known as the Age of Armageddon, nearly destroying both the human race and Sera. The humans rejected war and embraced a new era of peace, the Era of Silence, leading to a period of advancement of arts, science, and culture. But the shortage of energy led the fragile planet to more problems. Imulsion, a phosphorescent and low-viscosity fluid that was discovered by an oil-exploration drill, was unusable as an energy source until Dr. Helen Cooper created the Lightmass Process, which enabled production of cheap energy from this previously useless substance, marking the beginning of the Gold Rush. The full implementation of this process guaranteed a new energy source and led to the elimination of the need for hydrocarbon and nuclear-based fuel. However, the extremely low price of Imulsion energy and the massive loss of revenue and jobs in the traditional energy-producing industries soon caused Sera's world economy to collapse. The few countries that discovered an abundance of Imulsion below their land shortly thereafter found themselves at war with the many nations who were not as fortunate, and the Era of Silence ended as the Pendulum Wars began.
