The Sha'tar
The Sha'tar are a group of powerful naaru who rule over a rebuilt Shattrath City. With the help of the Aldor and the Scryers, they lead the battle against Illidan and the Burning Legion. The Sha'tar, or "born of light," are naaru that aided the Aldor, the order of draenei priests formerly led by Velen, in rebuilding Shattrath City. The city was destroyed by the Orcs during their rampage across Draenor prior to the First War. Defeat of the Burning Legion is the Sha'tar's ultimate goal; the Sha'tar are aided in this war by the Aldor and their rivals, the blood elf faction known as the Scryers. The Aldor and the Scryers fight for the favor of the Sha'tar so that they may be assisted in their war by the naaru's powers. The entity that leads the Sha'tar is known as A'dal; he can be found upon the Terrace of Light in Shattrath City.Both Alliance and Horde players begin as Neutral toward the Sha'tar. Players can increase their Sha'tar reputation through various quests, by raising their reputation with the Aldor or Scryers, or by adventuring into Tempest Keep.
Reputation
Until HonoredReputation can be gained from Scryer/Aldor signet/mark turn-ins. The following will only grant Sha'tar reputation until you achieve Honored status: [Firewing Signet], [Sunfury Signet], and [Arcane Tome] for the Scryers; [Mark of Kil'jaeden], [Mark of Sargeras], and [Fel Armament] for the Aldor. In addition, these will require more turn-ins to produce equable Sha'tar reputation to the main faction. Note that this reputation gain does not show up in the combat log, but can be verified by looking at your reputation panel.
Reputation can also be gained by running Tempest Keep: The Botanica, The Arcatraz and The Mechanar.
Through Exalted
After exhausting the reputation rewards from Aldor/Scryer turn-ins and Mechanar runs, players may wish to complete the few Sha'tar quests available. In addition to the quests, instance runs in Tempest Keep: Botanica, Arcatraz and Mechanar will continue to grant reputation. At this point, it is probably more worthwhile to run these instances in Heroic mode.
