Go to Old Master Kakaru in the The Pillars of Flame ( 1261, -107, -373 ) /waypoint 1261, -107, -373. He's a non aggro NPC. Take the carpet to The Giant's Field, head NE along wall and you will spot his camp between the roaming giants and the Raptor area. If you get to the raptors from carpet drop off you've gone too far.
He sends you to kill Thauz the Exiled, who can be found in northwest The Pillars of Flame, on the mainland south of the Char'Gin Island ( 1448, -96, -1214 ) /waypoint 1448, -96, -1214. Take a group with you, this Orc has a nasty opening AoE melee. If I were to guess his class he's a 'zerker. His camp is atop the rock formation there, ramp up to it is on the west side of mountain.
Return to Master Kakaru.
Go to The Living Tombs for a tablet update. This is a clicky, and is found in the Priestess Court. Easiest way to describe it is, looking forward, jump down from aqueduct into pool, make a 90 degree left turn, step out of pool, make another 90 degree left turn, tablet will be up against base of the support pillar for the above structures ( -283, -10, 174 ) /waypoint -283, -9.8, 174.
Again return to Master Kakaru.
3 Succulent roots, T6 common root. (Note: This step will update off any succulent roots you have in the bank, however you will need 3 in your direct inventory for the next step to update properly).
1 Indium infused stone dropped off Sandscrawler goblins (located in pillars near scrawling cliffs) I found them at ( 158, -98, -1070 ) /waypoint 158.24, -97.51, -1069.89 from Sandcrawler Miners. Any of goblins can drop them, though.
Return to Old Master Kakaru. As mentioned above, you MUST have all the required items in your inventory for this step to update.
Wait for Old Master Kakaru to craft the spirit vessel (this takes a minute or two), then hail him to receive it.
Head to Pirate's Perch in Sinking Sands to find the burial mound of Nukhatam where you must bind his spirit to the Spirit Vessel. The stairs to climb the cliff are located at (-2014, -230, 8) and the burial mound is found at ( -2077, -152, 5 ) /waypoint -2077, -152, 5. The Spirit of Nukhatam will spawn, he is a level 55 ^^^ Heroic Mob. Kill him, and you will get a Bound Spirit Vessel.
