Read The Chronicles of Riddick: Ghosts of Furya Page 5

None of them were surprised when the second civilization came up empty, minus the abundance of skeletons and ruined spaceships. Just to be thorough, they performed two different thermal sweeps, x-ray, sonar, and electromagnetic scans, and even a mineral scan to check the ground for manmade layers under the dirt and limestone. Every last scan came up with nothing. Absolutely nothing. The squad physically searched the ruins for clues and artifacts to study back on Earth, too. They took a few pieces of old technology that looked all Furyan but beyond that there were no further answers; just one big puzzle and Riddick as the lone survivor. And what were the odds of them finding him like that anyway?
