The Tau'ri science ship the Nicolas Tesla,was in orbit of the planet Tollana, the world of the Tollen ,the Tollan had been attacked by the Goauld, it was believed that the Tollans had been completely wiped out,the Tesla was to survey the planet ,and determine if there was any chance that some of the Tollen had survived , the sensors on the Tok'ra Tel,tak ,that had scanned the planet after the attack, were primitive compared to the systems, on the Science ship the Nicola Tesla, the ship scanned the planet searching for Tollan life signs ,in the mountains deep inside an extensive system of caves ,the powerful sensors of the Tesla ,detected the life signs of the Tollan Survivors, the Tollan had once numbered in the millions, until their world was destroyed in a cataclysm ,and they had been saved by the Tau'ri, and the Nox had recovered and relocated the Tollan, only numbering fifty thousand, that had Survived the catechism, now the Tollan race had been reduced to five thousand, the last remaining Tollan people .
After the collapse of the Tollan world ,at the hands of the Goauld, the survivors had gathered together ,and collected all the technology that they could salvage, from the ruins of the once great city of Tollan technological superiority.
They had scraped together the materials, that had sustained them since the fall of their civilization,the caves had become the home of the Tollan people ,and with the technology that they had recovered , they had transformed the caves into homes, and had built a town inside the large cave system, they had lighting ,and hydroponics to grow food, they had water and the basics to survive but that was all .
The atmosphere outside of the caves had became toxic to breathe, the bombing of the Tollan world, by the Goauld had caused massive eruptions around the planet to occur ,and now the atmosphere was toxic, history had seemed to repeat for the Tollan , they had found themselves in the same situation again, the survivors of a catastrophe on a world that was dying, the Tollan people had long ago, given up any hope of being rescued, the Stargate had been destroyed in the attack ,and they had nothing to build a new one with .
On the bridge of the Tau'ri science ship, the sensor information showed clear signs of life, that had been detected on the planet below .
The commander of the Tesla, contacted the high council and informed them that there were five thousand Tollan survivors ,the council would dispatch the ships of the Red Cross, to the Tollan world immediately , the last of the Tollan would be saved , the Red Cross would arrive in the next few hours and the evacuation would begin , the Tollan would be taken to Lemuria for the time being.
