I did another google search today for Ogdrul The Seeker. Few weeks ago I did a search only for Ogdrul without adding The Seeker after it in the search bar. It came up with nothing useful at that time. My search today only came up with 1 result for the wowhead NPC page for him. At the top of the google search it said it's usual did you mean.... Ogdru The Seeker. So I decided to check that out to see if there could be any references to this NPC. Found a lot of links referring to Hellboy. One in particular was for Ogdru Jahad. Which has some interesting information in it.

The Right Hand of Doom is Hellboy's right hand; the large stone like one.The Ogdru Jahad are fictional characters in Mike Mignola's Hellboy comic. They are the Dragon of Revelation, and are destined to bring about the end of the world. Though the Ogdru Jahad are the ultimate antagonists in the series, they are not themselves active, their release from imprisonment instead being the object of many other villains' plans. They were imprisoned in their Golden Cocoons by the Right Hand of Doom shortly after the creation of Earth, but not before they spawned 369 children, known as the Ogdru Hem.
Something else interesting, maybe a clue to what we're looking for is this:
Great Old Ones = Old Gods???Mostly inspired by the Great Old Ones of H. P. Lovecraft's Cthulhu Mythos (with some ancient Egyptian and Babylonian influences as well) the Ogdru Jahad are serpentine/crustacean entities which once resided on, and presided over, Earth. They are pitiless, chaotic, bent on destruction and subjugation and often so horrific in appearance that the mere sight of one of them sometimes induced madness. They are listed as follows:[1]
Amon-Jahad
Adad-Jahad
Namrat-Jahad
Irra-Jahad
Checkout the link if you think it might be pointing in the right direction. Or I could just be reaching and grasping for anything at discovering what this guy is for.
