The Visigoth System was a one-system star nation in the Solarian League and the location of the Visigoth Wormhole Junction.
It was located about 60 light-years from Sigma Draconis System. Its wormhole junction, of which one terminus connected it to Mesa, was discovered in 1454 PD. (SI2)
Unknown to most, Visigoth was actually a Mesan Alignment puppet state, as its president, Roman Hitchcock, was an Alpha line enhanced human whose family had infiltrated the system generations earlier. (HH12)
