The game builds it when the game starts, there are no saved "stock" empires in stock SEV. It would be kinda pointless with all the rule variations, point variations, tech points ect to try and make a "stock" set for each scenario outside of quickstart, so the game auto builds you an empire with the race style you choose when you quickstart.

You can quickstart a large game with each race, use the "master" password to take over for the non player empires, save all the empires as outlined above in fyron's post and use them as "canned" races, but you're better off getting to know the traits so you can build your own effective empire. If you're doing single player, you can still have AI empires randomly generated too.
