Tobin system

The Tobin themselves are extinct; but their legacy includes a vast minefield surrounding their homeworld. The mines are programmed to target certain energy frequencies, including Goa'uld weapons fire. It is the perfect neutral ground for the Goa'uld to meet; if one fires, his ship will be assaulted by the large mines.

But the Tok'ra have possession of a Tobin technical manual for the mines, which they cannot entirely translate because it is based in Phoenician. Apophis and Heru-ur used this sytem to discuss a potental alliance, but was interupted by a Tok'ra plot.
