Ikt is located in the Mensix Mining Facility's Cantina. Once you accept the quest head to the small island to the west of the Central Volcano at around -1680 160. Around that area (May take some searching...) you will find an Altar that has an Inspect option on it. This will spawn an NPC whom you will talk to, then fight. (84 Elite Jedi, Armor Break Root, Snare Immune) After you win (No losers here) you will then be able ot Use the shard on the Altar. Return to Ikt for reward.
