This improved Apocalypse was given as price to the four members of the winning team of the "Amarr Succession Tournament" in 2003. One more was given away in a BIG lottery in 2004.
Three "Impocs" have been destroyed in game - one of them was in fact destroyed in the Alliance Tournament III in 2006. The one that was given away in the lottery, was decided by players to be centre of a roleplaying event soon after, where it ended up with the Amarr empire and removed from the game.
Only one specimen remains and it is invaluable. DigitalCommunist is listed as the owner by Entity.
