Brocelind Plain is a region of the Shadowhunter home country, Idris. The plain is a flat terrain of high grasses which connects the shores of Lake Lyn to the Brocelind Forest and, thus, Alicante. 
== History ==
Apparently, the Greater Demon Armamos fought Jonathan Shadowhunter on the plains.
Brocelind Plain was the site of the Mortal War - the battle between Valentine Morgenstern's demons and the allied Shadowhunters and Downworlders - in late 2007.
Whilst waiting for the Clave's decision on whether to surrender or fight Valentine and his demonic army, the Downworlders arrived at the gates of Alicante to await their decision by sundown. Clary Fairchild was able to create the Alliance rune, allowing the Shadowhunters and Downworlders to bind together to share each others' fighting skills, speed, strength, and agility during a battle.
Once everyone was Marked, Magnus Bane created a Portal that transported all of the fighters to Brocelind Plain where they fought Valentine's army of demons summoned from Hell. 
Simon Lewis was fighting in the battle of Brocelind Plain when he accidentally fell into a ditch, where he later described to Clary as "the worst ten minutes of his life." However, due to the events that took place near Lake Lyn between Valentine, Jace, Clary, and the Angel Raziel, Valentine was killed and all of the demons vanished.
Unfortunately, there were still many casualties among the Nephilim and Downworlders, despite the battle of Brocelind Plain only lasting minutes.
