For the past few weeks, Imperium forces have been probing for a weakness in the Northern defenses. The first major strike occurred on August 1st as a Northern Coalition Keepstar in the system of X47L-Q was coming out of armor reinforce.
At 1900 EVE, Imperium forces began pouring into the system, committing the entirety of their supercapital wing. Roughly a combined 540+ titans were put into play by both sides as well as roughly 510+ supercarriers. A total of 10 trillion ISK was destroyed in this battle making it the largest in EVE Online history.
