Lightning Sons

The Lightning Sons seem to be a group of far seers in Nagrand, Outland. They are part of the Mag'har. They send Horde players to Sunspring Post, the only other settlement of Mag'har in the area besides Garadar, to fight the enemy — the Murkblood tribe of Broken — who have taken it over.

In one of their quests, you meet the enigmatic Saurfang the Younger who Farseer Corhuk refers to as a "youngling".

Speculation

 * They may be members of the Lightning's Blade clan.
 * In Hellscream, an old saying related to the Stones of Prophecy is "Only those with thunder in their hearts receive guidance through the storms of fate." This may be describing the Lightning Sons.
