Ivor Prime
Ivor Prime was the inhabited prime planet in its system and was home to a Federation colony. 

In 2373, the colony was destroyed by a Borg cube en route to Earth, as part of another attempt at an invasion of the Federation. Deep Space 5 informed Vice Admiral  of the colony's fate, who then passed on the news to Jean-Luc Picard in 2373. ()
