Viamarr 4, found in the Inner Rim's Viamarr system, was a planet. Velery served as the main city, acting as its capital. The planet's underground caves were used for cultivating Viamarr Blackroot fungus.
Wraith Squadron made a stop on the planet in 7 ABY. This occurred in the initial period of the New Republic's campaign against the Warlord Zsinj, following their acquisition of the altered CR90 corvette, the Night Caller (Esson Strike). Governor Watesk governed the world at this point, and was working to align the planet with Zsinj. Viamarr 4 possessed a limited air wing, Blackwing Flight, which was composed of obsolete Z-95 Headhunters at the time of 7 ABY.
