After the Isor-Tsan Kiri War and the disaperance of the remanents of the enemy Tsan Kiri it was some time before the Isorians were to discover an abandoned hatchery of what wer to become known as the Tsan Ra.
Biologically a form of the silicate creature the Isorians called the Tsan Kiri. These newly discovered creatures were born into the shard of the Isorian Senatex. Because the Isorian IMTel had already absorbed data from Tsan Kiri bio-spores, the melded nanosphere was perfectly adapted to interface with the new hatchlings. The creatures eﬀectively became part of the Isorian shard in the same way as the human populations of the Senatex. In a strange way the Tsan Kiri were reborn not as enemies but as part of the Isorian shard itself. To distinguish them from the Isorian’s former enemies the new human-inﬂuenced race became known as the Tsan Ra.
The physical prowess of the Tsan makes them eﬀective troopers in countless combat situations. Their psychological make-up is in many ways more compatible with the business of waging war than is that of Isor’s human population.
