Cisco Air operating a Behemoth Class Crusier ap1121g, THE KERBEROS, a k9 io setup out of the Boise Spaceport. The place where THE KERBEROS kept watch was according to some at the mouth of the Acheron, and according to others at the gates of Hades, into which he admitted the shades, but never let them out again.
Carney Airlines, founded by Walter Carney, was formed in Boise in the 20th century. The company is the root of present day OverUnity Transitlines, which still serves the city at the newly renovated and upgraded Boise Spaceport.
OverUnity Transitlines has traditionally monoploized the travel up and down The Double-Tree. A major trans-dimsional mutli-directional node passes through the wooded river valley. OverUnity Transitlines contracted out transit lines through mouth of the Acheron and at the gates of Hades to Cisco Air.
Cisco Air was founded as the air support for a private security company, that has been since co-opted by the intelligence service. The role they play at mouth of the Acheron and at the gates of Hades is a quasi-military one and is often classed as a private security zone.
