The Psionic Masters: The Zhodani in Traveller

When Traveller first released in 1977, it did not have an official setting. This quickly changed with the introduction of the Third Imperium, a large, multi-star system empire. While alien species like the Hivers, Droyne, Aslan, Vargr, and K’Kree — out of many — are prominent features in many Traveller campaigns, the fact is that the Imperium is human dominated. And the Imperium’s two major foes, the Solomani Confederation and the Zhodani Consulate, are human dominated.
Part of the setting’s lore is that the so-called Ancients took humans from Earth and seeded them throughout what is called Charted Space. Often, the humans have been altered radically for the environments. Cafadans, Darmine, Darrian, and others were either altered by the Ancients or adapted to their environments and managed to survive after the Ancients destroyed themselves in a cataclysmic war.
The Zhodani, however, occupy a special place in the Traveller setting. While transplanted by the Ancients, they discovered the faster-than-light jump drive on their own accord. More importantly, they are the only human society that incorporated psionics into their culture and government. This has had a profound effect on them and on the Imperial perception of them when the two civilizations clashed in the Spinward Marches, a designated area of space.
