The Shadow Labyrinth Key drops from Talon King Ikiss in Sethekk Halls. It is available to everyone in the party who does not already have it.

This key is only to open the south gate in Auchindoun towards the Shadow Labyrinth. It is not necessary to have the key in your possession to enter the instance gate.
