Typically described as having a long blonde braid of hair down her back, wearing a man's coat and trousers, and being deadly with a bow and arrow, Birgitte Silverbow is the heroine of many hundreds of gleemen's tales and legends. Like many of the great heroes of the Wheel of Time, she has been "spun out" into the Pattern many times, taking a different name but always following the same pattern: an archer, sometimes a soldier, who is linked to a lump-faced man who fights with two swords (most famously known as Gaidal Cain), whom she at first hates but eventually falls for. She is also one of the Heroes of the Horn of Valere, and, like Artur Hawkwing, like Gaidal Cain, like a hundred other heroes, can be summoned to fight for he who blows the Horn.
When not being woven into the Pattern, or fighting in spectral form, she and all the other heroes of the Wheel reside in Tel'aran'rhiod, and it was there that she first made her acquaintance with Elayne Trakand and Nynaeve al'Meara. The two were hunting Darkfriends in the World of Dreams, and despite injunctions to the contrary (and the ridicule of Gaidal), she insisted on stepping in. This led, eventually, to a confrontation with Moghedien in which Birgitte was ripped bodily from Tel'aran'rhiod and expelled directly into the waking world, instead of being born (re-incarnated) into it normally. When Nynaeve and Elayne found her, she was dying, a condition not even Nynaeve could heal. Elayne, with no other recourse, bonded Birgitte as her Warder, which saved her life, and Birgitte has served in this capacity ever since. Deadly and unspeakably competent with a bow, she is also by far the most raucous of Elayne's entourage; she and Mat Cauthon share a fondness for drink, carousing and foul language, a friendship strengthened by Mat's memories and the fact that he is the Hornsounder.
Birgitte is an oddity in several respects. She is one of the world's only female Warders--both she and Elayne have discovered at first hand that the bond of their shared gender increases the empathic link of the Warder bond to sometimes unacceptable levels (when Birgitte gets drunk, Elayne gets tipsy, and likewise when Elayne and Rand spend some time alone, Birgitte gets... disturbed, to put it mildly). She is also the first Hero of the Horn to have been expelled from Tel'aran'rhiod: she still has the memories of all her past lives, though as time passes they are beginning to blur together. Finally, she is intimately linked with Gaidal Cain, having shared a storied romance in their incarnations from the Age of Legends, and apparently in previous incarnations as well; though she hides it for the most part, she fears that her return to the real world through expulsion rather than reincarnation has broken the cycle of their love.
