Turon

"The Turons were the first species to ever encounter the Flood and lived to tell the tale. The Turons fought for every inch of land they owned; something the Forerunners or the Covenant never accomplished or even reacted to. The Flood actually never recovered from their defeat, and infact without the Turon's damage, the Forerunner would have never managed to build the Halo Array."

- A Forerunner description of the Turon species.

The Turons (nicknamed Sacri 'shon (Vigilant Warriors) by the Forerunners) are a race of highly intellegent, slender humanoids native to the Milky Way Galaxy. They were the first species to encounter the Inferi Redividus (The Flood). Unlike the previouse species before them, the Turons prevailed against the Flood, forever weakening the Flood's power.
