Atiesh, Greatstaff of the Guardian

Atiesh, Greatstaff of the Guardian is a staff currently wielded by Med'an. It was born from the "seed of hate" and grants its wielder "power unending". It was passed down by each Guardian of Tirisfal to its successor.

Atiesh can be used to open up portals to Karazhan and is also known for attracting ravens towards the wielder.

History
Its date of creation is unknown, but it is known that Atiesh was forged from the "seed of hate" and was wielded by each Guardian of Tirisfal until the line ended with Medivh. This would set the age of Atiesh at thousands of years.

Following the assassination of Medivh, the staff was brought to Dalaran where it was held by successive members of the Kirin Tor, who all found their deaths soon (except for highborne sorcerer Tarsis Kir-Moldir, it appears ). After all these deaths, it was decided that the staff was to be put "behind impenetrable barriers of magic" and a "watcher" was appointed: Angela Dosantos. The shattering of the staff came about following the destruction of Dalaran by Archimonde, probably due to the failsafe system of the magical barrier. Atiesh was shattered into forty-two pieces which were scattered across all of Azeroth. Brann Bronzebeard held the, which he somehow lost to C'Thun. The Scourge captured the forty-one other pieces, twenty of which were initially held by Tarsis. Forty pieces of Atiesh were each entrusted to a different lieutenant of Kel'Thuzad within Naxxramas, while the fallen mage himself held the staff's head.

When Naxxramas appeared over the Eastern Plaguelands, the Argent Dawn attempted to prevent this powerful focus of power from falling into the hands of the necromancer-lich, Kel'Thuzad, and were apparently successful in this regard.

Later, Meryl Winterstorm sent Garona Halforcen on a mission to retrieve the base of the shattered staff from within the remains of C'Thun. Garona succeeded and gave the base to Med'an, who restored the whole staff simply by holding it while being imbued with the powers of the New Council of Tirisfal. .

In World of Warcraft
Atiesh, Greatstaff of the Guardian is a caster staff which could be assembled via a quest prior to the release of Patch 3.0.2, when Naxxramas moved back to Northrend. The quest begins inside Naxxramas and involves obtaining several parts of the staff.
 * The staff could be obtained by mages, warlocks, priests, and druids.
 * The item stats vary slightly for each class.
 * The cloth portion of the staff varies based on which version it is: green for druids, red for mages, white for priests, and blue for warlocks.
 * The staff provides the ability to open a portal to Medivh's tower of Karazhan; however, at the time of Atiesh's release into World of Warcraft, Karazhan had yet to be implemented. It was opened upon the release of Burning Crusade. The portal leads to the front door of Karazhan.

Assembling the staff

 * Kel'Thuzad's underlings in Naxxramas each have a chance to drop a.
 * Once all 40 Splinters have been found, they may be combined into the, which gives a quest to visit the dragon Anachronos. Players were then given a quest to obtain the staff head and base of Atiesh. They had to be at least neutral with the Brood of Nozdormu to be able to talk to Anachronos to complete the quest and hence be able to pick up the following quest to obtain the head and base.
 * Kel'Thuzad drops the.
 * The drops from C'Thun in the Temple of Ahn'Qiraj.
 * The final step was going to Stratholme to cleanse the staff, followed by slaying Atiesh. The summoning location was in the Festival Lane west of the Alonsus Chapel, in between the western ("Scarlet") and eastern (Scourge) districts of Stratholme.
