Arya™

Arya Dröttningu [often called Arya Svit-kona] is a female elf, the daughter of Queen Islanzadí Dröttning and her husband Evandar, and therefore a princess.
Arya was banned from Islanzadí's presence because she chose to devote herself fully to the cause of the Varden. She was appointed the courier of the one dragon egg Brom and Jeod had managed to recover from Galbatorix's clutches, and spent 15 years conveying the precious egg back and forth from Farthen Dûr to Ellesméra, in the hopes that eventually a new Dragon Rider would be found.
Galbatorix somehow got wind of this arrangement , and sent the shade, Durza, to ambush Arya and recapture the egg. The Shade managed to accomplish the former, but failed the latter, for Arya teleported the egg into the wilds of the Spine, intending that Brom, in Carvahall, would find it. Instead, the egg came to Eragon, and Arya was imprisoned in Gil'ead.That is where she underwent torture, refusing to reveal any information about the Varden or the Elves. Each day, she was given a dose of a deadly poison, called Skilna Bragh, that would slowly kill her while undermining her magic abilities.
When Murtagh and Saphira staged a daring rescue mission, Eragon insisted that Arya come along with them, despite the difficulties this might incur upon their travels. When Eragon attempted to heal her, he found she was branded, whipped, and beaten. Arya remained in a self-induced comatose state, which slowed the effects of the deadly poison within her. Mentally communicating with Eragon, however, she informed him that unless they could reach the Varden, who had the antidote - Tunivor's Nectar - she would die within three or four days.
They managed to reach the Varden in time to save her, and she was healed sufficiently to fight when Farthen Dûr came under attack from Urgals and Kull. During the battle, she saved Eragon's life by distracting Durza with the breaking of the Isidar Mithrim, though her action earned her the dislike of the dwarves.
After the battle and the havoc wreaked by the death of Ajihad, she accompanied Eragon to Ellesméra, where she was reconciled with her estranged mother. Her feelings towards Eragon, however, began to grow cool, as he approached her with unwanted admiration. Following the Blood-Oath Celebration, she returned to the Varden, and aided them in preparing for attack by Galbatorix's forces. She fought at the Battle of The Burning Plains. She was, along with Nasuada, the first one to know that Eragon was Morzan's son.
Arya's family was one of the several royal houses in Ellesméra. The House of Dröttning, which line possibly dated back to Queen Tarmunora, had been in power for many years. Tarmunora was succeeded by Dellanir, Arya's grandmother, implying that Tarmunora was a Dröttning. However, she could have handed the throne to another royal house, as Elves sometimes do. Dellanir ruled for centuries before voluntarily abdicating in favor of her son, Evandar. Evandar then became king and mated with an Elf princess, Islanzadí, who gave birth to Arya. Evandar died at the hands of either Galbatorix or one of the Forsworn about one hundred years before the Rider War, and Islanzadí ruled after him.
It is unclear how many family members Arya has apart from her mother; she has no brothers or sisters. The only other Dröttning mentioned, and that only in passing, was named Niduen. Niduen sent a gift to Eragon when he arrived in Ellesméra, but it is uncertain what relation Niduen was to Arya.
