@TheEdVerse, why didn't the Netherese exterminate the remaining orcs in their territory after Ioulaum's first campaign against them? They'd suffered from orcs for a long time. Ioulaum's campaign was costly, but when the enclaves rose and Netheril grew in power, why'd they stop?

They didn’t stop, but their extermination efforts became increasingly brief and slapdash (and therefore, were failures) as they got interested in their various projects. (The downfall of the Netherese was their decadence; they hunted after many sorts of power, 2)
…these hunts consuming their energy and thinking, so like all fanatics they increasingly left the practical, everyday world behind. As orcs did what orcs have always done: endure, no matter what, and breed like rabbits, so they're VERY hard to wipe out.#Realmslore
