"I don't really know all that much, honestly." Trunks said, reaching up to brush at the back of his neck. "Most of what I know has come from Mom, and a little bit that I can pry from Father."

Still, most of these came while Trunks was working and Esteban was keeping company. So Trunks started moving to clear stuff away. "I know they were a warrior and soldier race, enslaved by a galactic warlord named Freiza. Which doesn't mean necessarily that the saiyans were nice to begin with--I get the impression they weren't. But that heritage is still part of me, so it's important to know. Frieza feared them getting strong enough to over throw him though, so he did his best to wipe them out. Nearly succeeded but for a small handful, of which only 1 wasn't in his service."
