Both Ends of the Killmail Wear the Same Tag
There is no fleet here and only one loss to argue over. One pilot lost a capital; another is credited with finishing it. Both are listed under Weapons Of Mass Production., which is also the only organisation recorded on both the attacking and losing side of this killmail. That is what the record shows: a capital ship destroyed, and the credit for its destruction sitting inside the same organisation. What the record does not show is why. A single killmail is a receipt, not a transcript, so treat any explanation you invent for it as yours, not the data's.
One Pilot, One Kill, an Awkward Price Tag
The scale of the event itself is tiny - one system, one killmail, two pilot IDs - and it would barely register if a frigate had been involved. The cost is what makes it worth a second look. At 14.5B ISK, the Bane is a capital-class loss of the kind most pilots go an entire career without personally funding. It is the only loss recorded here, and there is no evidence in the source of a wider engagement around it. Whatever happened in P-ZMZV, it happened quietly, and someone is out a very expensive hull.
