An odd place, Westfall both borders Stormwind, and is populated by humans not under the Alliance’s complete control. The region was stolen right under the Alliance’s nose by its own bitter people. This rich land has lain fallow since after the Second War, but it is now held by the Defias Brotherhood. Stormwind claims the land as its own, but it has found little time to be concerned with it, with insufficient funds and might to retake the region. A handful of farmers still try to keep their land, and some even attempt a tithe to Stormwind every year, but most only grow enough to feed themselves. The Defias Brotherhood controls much of the region, focusing in the southern area of Moonbrook.LoC 60
Once a rich agricultural center, much of Westfall now lies fallow and forgotten. The Defias Brotherhood, renegade humans who wield secrecy and technology against Stormwind, control much of the area. Bandits and gnolls raid those farms that remain, and Stormwind’s resources are stretched too thin to protect the beleaguered populace.WoWRPG 16 Westfall has the mild temperatures of Elwynn, but winds batter it both from the sea and from Duskwood. The bare farmlands add little to break the wind, which can cut through clothing on a blustery day.LoC 60
Westfall is a a region of rolling pastures and farms that was once beautiful and green, but now has become barren with drought and maltreatment at the hands of bandits. The grass is yellowed and the fields are infested with ravenous carrion birds and mechanical harvest watchers gone rogue. The outlawed Defias Brotherhood has gained a strong foothold in Westfall, and controls several camps and farmsteads in the area. It is rumored that these bandits possess a large mine with an entrance somewhere in the small town of Moonbrook, and that they have connections with the kobolds that occupy the Jangolode Mine in Westfall and the various mines in Elwynn Forest.
The defenders of Stormwind have erected a last bastion of military power in the region at Sentinel Hill, from where they issue commands to anyone willing to aid the cause. Although most of the area's farms have fallen to disrepair and passed into control of the Defias, there are still a number of farmers who bravely (and desperately) cling to their holdings in spite of overwhelming odds.
Also note that on PvP servers high-level Horde players enjoy killing humans in Sentinel Hill.
