One Killmail, Two Names and a Very Large Number
The loss is logged against GM Wren, whose recorded organisation is C C P Alliance. Black Ribbit is the only attacker organisation named in the record, and Xanderfall Audeles is the pilot credited with the final blow. That credit is precise and narrow: it identifies the last shot on this killmail, not who contributed the most damage to the kill. No per-attacker damage breakdown is supplied, so the honours stop there. What remains is the figure - 136.7B ISK for a single supercapital, the kind of loss that outlives the memory of the fight that produced it.
205 Names on the Record, One Loss in It
Black Ribbit also appears as the attacking organisation, and 205 participants appear in the record overall. That is a lot of names attached to one confirmed kill, and they deserve care: the participant figure describes everyone the records name, not a verified headcount of pilots who fought, and a single killmail confirms a single loss rather than the shape of the engagement around it. Nothing in the evidence establishes how the Avatar was caught, what else was on grid, or what happened afterwards. Tarta's record shows an expensive supercapital destroyed and a final blow credited to Black Ribbit; the rest of the engagement simply isn't in this data.
