The Hordeline is a former, fortified border running between the nation of Lastwall and the orc tribes of the Hold of Belkzen. It was constructed around 4515 AR and consisted of crude, earthen ramparts and palisades. It ran from the Mindspin Mountains along the southern edge of the Kestrel River, then headed northeast to end at the River Esk. It was overrun two years after its construction, in 4517 AR,1† by orc forces who pushed the border further south to its current position.234
