Praxeon
From The Stargate Omnipedia
Planet in the Milky Way Galaxy under the control of the System Lord Baal. It was on Praxeon that Baal enacted his ultimate plan for galactic domination, using the planet's Stargate and intelligence stolen from Earth to construct a time travel device inside a huge silo.
It is not known if Praxeon is inhabited. The planet is relatively close to Earth, as it can be reached by hyperspace in less than a day.
