The station was taken by a Capital force that included according to sources, no less than 60 Slowcats (Archon Carriers) and 20 Super Carriers. Providence Bloc, unable to counter such an overwhelming force and witnessing this display for previous timers in the system, chose not to form. Thus the system was captured without a fight.

G-5EN2 is one of the 4 pathways connecting the region to Empire space. With it and the Y-MPWL system in the hands of [NC], the pressure on the Providence Bloc logistics may be felt soon. This also raises a concern that the KBP7-G system will be targeted next, as fighting occurred over it in the past between the two entities.
It remains to be seen what will happen, but one thing for certain, [NC]'s facade of a "Fun War" has been completely shattered following last week's aggressive push. [NC] has brought only Slowcat fleets and Super Carriers to all the timers, making it obvious it was not looking for a fight, but a complete victory.
Perhaps the string of humiliating defeats and inability to find a definite counter to Providence Bloc's Naga Battlecruiser doctrine have finally taken their toll on the [NC] leadership. Regardless, the name of [NC] has lost much of its merit in the last few weeks. By the time the new sovereignty changes will be implemented, it may lose all of its value.
As the fighting continues, the EVE Scribe will keep you posted on further developments.
