Blast the Gateway - Quest - World of Warcraft
This quest is a Daily Quest for the shattering sun offensive available from:
Magistrix Seyla - NPC - World of Warcraft
This quest is fairly simple to do, especially at level 80: you go around and kill 8 Incandescent Fel Sparks which is ridiculously easy especially for a clothie at 80.
But the quest awards the item Shattered Sun Supplies - Item - World of Warcraft which before 4.0.1 gave Badges of Justice, but now gives 5 Justice Points a day.
Sidenote:
Postscript:To complete the quest, you need to take the Unstable Living Flare to the gate at 58,18, where you got teleported as part of the initial quest The Missing Magistrix (The Missing Magistrix - Quest - World of Warcraft).
