Zed Lapis sector
From Memory Alpha, the free Star Trek reference.
The Vagra system is located in the Zed Lapis sector.
In 2364, the USS Enterprise-D was traveling through the Zed Lapis sector to rendezvous with Lieutenant Ben Prieto and Counselor Deanna Troi who were aboard shuttlecraft 13 returning from a conference. The shuttle began experiencing an onboard systems failure and crashed on Vagra II (also located in the Zed Lapis sector). (TNG: "Skin of Evil")
