Player Killer and Player Killer Lite Arenas were introduced during the event Reprisals as a way of getting player killers out of the marketplace. Can be recalled to by using the /pkarena and /pklarena commands after using either an Altar of Bael'Zharon or an Eye of Darkness, or for PKL by simply typing /pklite. The Reprisals Letter to the Players mentioned it being updated as the months go but it still remains a featureless box except two statues of Bael'Zharon.
