There has been some debate in the roleplaying community and generally with those interested in lore about who this bow belonged to and what makes it a legendary quality item, beside the stats, of course. Some believe it's the bow of Alleria Windrunner, judging by the model of the weapon which is highly reminiscent of High elven style, the yellow description it has and other loot Kil'Jaeden drops - among them is Coif of Alleria.
