Meridian trench/Legends

A Meridian Trench, located on the DS-1 Orbital Battle Station, was a trench encompassing a portion of the station. It also housed the station's greatest weakness: A thermal exhaust port that would cause the Death Star to under go a critical chain reaction if weaponry was fired into it. The Rebel Alliance utilized this trench to try to destroy the Death Star before it could destroy the Rebel base on Yavin 4.
