Brood of Nozdormu

You can up this reputation by killing monstrers in [zone=3428] (raid 40 of course).

To do it quickly, here are some ideas:

• 
  
• The repetable quest Mortal Champions which consists in bringing back a [item=21229] that you can find on every boss. You'll earn at least 500 reputation's points
• 
  
• The 3 repetable quests for your class (by example [quest=8592]), with a reputation at least neutral (for shoulders) and friendly (for head and feet). You'll earn at least 500 reputation's points
• 
  
• The repetable quest Secrets of the Qiraji that starts with [item=21230], that you'll find on every mob (droprate is ~2%). You'll earn at least 1,000 reputation's points
• 
  
• The unrepetable quest The Savior of Kalimdor, but which will give you 1,000 reputation's points, plus 500 reputation's points for the prerequisite quest C'Thun's Legacy. That starts with [item=21221], that [npc=15727] drops
• 
  

Repetable quests Imperial Qiraji Regalia and Imperial Qiraji Armaments requiring 3 Elementium Ingot each one for 500 reputation's points... In my opinion, you should avoid these.

Good game =)

The Brood of Nozdormu is the faction for reputation from the Ahn'Qiraj raids, in Sithilus, Kalmidor.

Copy/pasted from other site:

There are 4 additional ways to gain reputation with the Brood.
- by killing the Broodlord in BWL and looting his head, you can collect silithid fragments from the bugs in Silithus inside the hives and hand in 200 of them for 200 reputation.
- mobs in AQ40 untill 2999/3000 Neutral
- insignias dropped from all AQ40 bosses that you hand in for reputation
- artifacts that drop from random mobs in AQ40 that you can hand in for 1000 repuation.
