LORE

The events that have lead the three races to this point is part of a long history that began more than 10,000 years ago. As Sins of a Solar Empire has expanded, this march forward through time has continued....

10,000 YEARS AGO

he Vasari Empire ruled over countless worlds. Relentless and unstoppable, their Dark Fleet sought to eclipse ever more civilizations until a cataclysmic error brought it all to an abrupt end. With their worlds destroyed and their species all but wiped out, the survivors began a desperate race to outrun their past.

1,000 YEARS AGO

uring the formation of the Trade Order, emissaries found a single world orbiting a giant red star on the periphery of what was to become Trader Space. The people of that desert planet were eventually found to be practicing the utmost in scientific and social deviancy; ancient taboos long since assumed to be law. Shocked and disgusted, the Trader Worlds conspired to have their forgotten brethen exiled far outside the territory they were claiming as their own.

30 YEARS AGO

he Trader Worlds prospered in an era of lucrative trade and relative peace. Stories of their ancestors’ wars had long since passed into the depths of the oldest archives; the methods and machines by which they conducted those affairs long since buried. Consequently, when the Vasari Exodus Fleet arrived, the outlying Trade Worlds paid dearly.

In a battle for survival, the Traders find a new impetus to rediscover the ways of their savage past.

20 YEARS AGO (Sins of a Solar Empire)

he Exiled have returned; a transformed people calling themselves “The Advent.” With a vast fleet of advanced warships and mysterious weapons, they bring a growing number of worlds under their control. The already struggling Trader Emergency Coalition finds itself caught in a two-front war that appears utterly hopeless.

15 YEARS AGO (Sins of a Solar Empire: Entrenchment)

fter nearly 15 years, the war which has raged across dozens of star systems neared a stand-still. The great fleets of the Trader Emergency Coalition, the Vasari Empire and the Advent approached stalemate. With the fronts temporarily stabilized, each race took the time to regroup and entrench. Great defensive battlestations were deployed and critical choke points fortified, while all sides prepared for an all-out offensive.

5 YEARS AGO (Sins of a Solar Empire: Trinity/Diplomacy)

ith more than a quarter century of constant warfare behind them, the factions began to look for alternative solutions to their conflict. Many of those in the Trader Emergency Coalition feared that their people were losing their identity, while others felt their leaders failed them after promising safety that wasn’t delivered. Some members of the Advent started to wonder if their course of vengeance was the right one to follow, while the Vasari simply wanted to escape the region with as many resources as possible. Such conditions lead to opening of talks between the three major races for the first time, in the hopes that their envoys would finally bring peace.

NOW (Sins of a Solar Empire: Rebellion)

hile many were hopeful that diplomacy would finally end the war, differing opinions on what should be done, along with the depleted power of the controlling factions, has lead to a splintering of the groups involved.

The loyalist members of the Trader Emergency Coalition adopt a policy of isolation, focusing on enhanced defenses to ride out the rest of the war. Those who rebel against the coalition take on a purely militant view, coming to the opinion that the only way to bring peace is by ultimately crushing all who oppose them - especially xenos.

For the first time in their history, the war creates a schism in the Advent Unity. The loyalists seek to continue their policy of revenge against the Traders, and to assimilate all others to the Unity’s influence. However, others amongst the Advent suspect that a corrupting influence from within has diverted the Unity from its proper destiny.

The divide created in the Vasari Empire is less pronounced, but just as severe to their people. With the Vasari now practically frantic to move on to new space, the loyalist faction abandons cooperation and decides to take the resources they need by any means necessary. Having accepted the need to work together, the rebel faction feels that their best chance for survival is to work with the other races and bring them along to flee the approaching enemy.

The Races of Sins of a Solar Empire

Trader Emergency Coalition

TEC

he Trader Worlds Enjoyed a golden era of lucrative trade and relative peace under the strict guidelines of the interplanetary Trade Order. They had forgotten their ancient history of war and replaced it with a future of endless prosperity. The arrival of the Vasari caught the Traders completely unprepared.

Advance exploratory waves from the Vasari Exodus Fleet, hastily crushed and colonized over a dozen worlds. Political infighting amongst the Trade Order representatives and the independent Opulentsia, delayed the first military response by months. Finally, they sent everything they had to repel the invaders; a cobbled band of ships designed to combat piracy. The untrained, undisciplined, and poorly equipped crews met a swift demise.

Disasters continued for years but, the resilient Traders slowly learned to apply their perfection of the economic engine into an ever more powerful war machine. Factories, trade routes, and savvy businessmen were now one with star bases, supply lines and master tacticians.

Unfortunately, the disastrously poor cohesion of the independently operated planetary fleets often negated this progress. As the Vasari approached the central worlds, it became clear that their advance could not be stopped without higher levels of coordination. The Trade Order could not fulfill this role because its mandate forbade interference with the sovereign rights of the member planets. Thus, the Trader Emergency Coalition (TEC) formed despite strong opposition to the loss of planetary autonomy.

United under one authority, the TEC finally stalled the Vasari advancement, but the reprieve was brief. Their deviant brethren, exiled one-thousand years ago, have returned with a colossal fleet of sophisticated war ships and now wreak havoc across the undefended sectors. With their entire force dedicated to maintaining the Vasari line, the TEC faces a near hopeless dilemma.
