Nerubian seer

Nerubian seers are a type of nerubians.

They were encountered by Arthas Menethil in Northrend and Azjol-Nerub during and after the Third War.

In the RPG
They have a valued place in nerubian society. They are the counselors and mages of the spiderfolk. The Scourge destroyed Azjol-Nerub's libraries, leaving the nerubians with whatever few bits and pieces the seers could carry off. They are interested in returning to the ruins to recover all that they can. Once skilled in architecture, accounting, law and other esoteric disciplines, the demands of life now require most seers to focus on magic to protect their communities. A seer often uses bits of webbing attached to its abdomen to hold spell components.

They are the intellectual backbone of the community. They are a tightly knit sub-community of arcanists who are obsessed with preserving lore and rebuilding their lost libraries. The boldest seers are also explorers, risking the undead plague to venture into ruins and find fragments of lost knowledge. They understand the outside world better than other nerubians, and make the best diplomats.

Workers who show mental talents become seers. Seers reach almost 15 feet in height and 13 feet in diameter.

Speculation
These seers were likely redesigned for Wrath of the Lich King to become what are now known as Nerubian viziers.
