The Long-lost Augari Treasure at coordinates (75,69) in Krokuun is "locked", the chest offers a hint that it will open for "one wielding the power that echos that of the Augari". Using the Shroud of Arcane Echos ability in front of the chest will allow it to be looted.
Shroud of Arcane Echos is one of four zone specific abilities that is selected via the Matrix Core in the Vindicaar. All locked treasures in Argus that have a purple coloured crystal hovering nearby can be accessed using Shroud of Arcane Echos.
Shroud of Arcane Echos is awarded to players who have completed the introductory quests in the Mac'Aree sub-zone and placed the Sigil of Awakening in the vindicaar.
The Long-lost Augari Treasure is at the Eastern edge of the Petrified Forrest under the cover of some fallen rocks and petrified trees.

Each of the four Matrix Core spells are colour coded, a coloured crystal near a locked treasure will let you know which spell should be used to unlock the treasure.
