UB5Z-3
From EVE History
UB5Z-3 is a solar system in Feythabolis containing the only original conquerable refinery station in the Feythabolis region. In 2005 it was the venue of many battles as the station was a key strategical target in the battle for the region, fought between the resident Xetic Federation by forces led primarily by MASS corporation, and also including The Five as part of a broader attack on all regions held by the Xetic Federation. Shortly after these battles the area was claimed by Ascendant Frontier as part of their split from Xetic Federation.
