Darkness in the Delimbiyr
This is the present-day name for the strip of inhabitable land west of Anauroch, and north-east of the Greypeak Mountains is now home only to monsters. There are rumours that persist of powerful mages inhabiting the southern end, and hurling back the evil creatures of Hellgate Keep with their art. Rumors of Zhentarim agents scouring the Fallen Lands for powerful magic from long-lost Netheril continue to circulate. And because of this, adventurers still abound in the Savage Frontier.
This was once part of the realm of Netheril, a kingdom that could not stem the magical dessication expansion of the Great Desert; some sages say that many of them set out south across the Realms to find a new home, and founded the present-day realm of Halruaa.
