Aran'gar/Halima Samarov Edit
After his death, the Lord of the Grave reincarnated Balthamel in a new female body naming him/her Aran'gar, the word originally meaning one of a set of dueling daggers, used in the game of sha'je , popular during the Collapse,
New Appearance Edit
Showing sense of humor the Dark One reincarnated the soul of this womanizer Forsaken into the body of an alluring Borderlander woman.
Aran'gar's new body is strikingly beautiful; her perfect face has big green eyes and glossy black hair. She often showed a large amount of her full, firm bosom.  She has an earthy, outspoken manner.
Curiously, she was still channeling saidin, which seems to show that it is the soul that determines which part of the True Source that is channeled, at least in the case of resurrection by the Dark One. That the soul has gender is a curious feature of Jordan's metaphysics, and is a concept not found in reincarnationist religions such as Hinduism and Buddhism from which Jordan drew many of his ideas.
Hiding in Salidar Edit
Aran'gar hides with the Salidar Aes Sedai marching on Tar Valon, using the alias Halima Saranov and working as secretary to Delana Mosalaine (a Black sister posing as Gray). She ingratiates herself with the rebel Amyrlin Seat Egwene al'Vere by providing the only relief to be found to the frequent headaches Egwene experiences via massages that sometimes left the Amyrlin "whimpering."  Unbeknown to Egwene, Aran'gar was causing them. During this time Egwene also frequently experienced troubled dreams that she couldn't remember on waking, an odd occurrence for a Dreamer. Aran'gar was likely causing these as well; this is confirmed later by Mesaana asking if she was too busy "playing playing your little dream-games with her that you forgot to find out what she was thinking?" during the Forsakens' meeting in Tel'aran'rhiod. 
Balthamel's fondness for physical pleasures has expanded since the resurrection, and as Halima, wears quite revealing dresses which cause quite a bit of comment.
Halima danced with Matrim Cauthon while he was in Salidar. After Mat decides that Halima is too forward and leaves her, Halima channels at Mat as he's walking away. The Foxhead medallion he wears goes cold, stopping saidin this time. Mat turns around, and sees Halima looking at him with a very surprised expression on her face, but only for a very brief moment.
Halima rescues Moghedien from the a'dam in which she is being held, which she accidentally touches. Egwene al'Vere who was wearing the bracelet at the time feels this. Halima murders Egwene's other two maids, Meri and Selame. She travels with the Salidar delegation to meet with various nobles along the border of Andor and Murandy.
Hiding spot revealed Edit
She participated in the Battle near Shadar Logoth. She is forced to retreat when she is attacked by Nesune Bihara, Daigian Moseneillin, Beldeine Nyram and Eben Hopwil. Hopwil is killed during the exchange when he detects her channeling saidin. While in the camp she murders Anaiya and her Warder, and Kairen Stang with saidin.
She attends the meeting with the other Chosen in Tel'aran'rhiod, which is made to look like the Ansaline Gardens. There she is told that Rand is not to be harmed and that Mat and Perrin Aybara are to be killed if found. She flirts with Graendal and entertains the notion of entering an alliance with her. When Moridin reveals that Sammael, or another Chosen disguised as him, had given orders to Myrdraal and Shadowspawn which sent them into the Ways, Aran'gar thinks to herself that she wishes she knew who was playing her own game. This suggests that she had begun posing as Sammael but still was not the one to have ordered the assault on Rand at Lord Algarin's manor. She was likely plotting to kill Rand in some other scheme, though, as she thinks to herself that Moridin was going to be "terribly disappointed" about not harming Al'Thor.
When Jahar Narishma came with a proposal from the Dragon Reborn Rand al'Thor to the Salidar rebel Aes Sedai about bonding forty-seven Asha'man, Narishma detects someone channeling saidin and warns them of a female Forsaken able to channel saidin. This causes Delana and Halima to flee the rebel camp. It is finally revealed that Halima was Sheriam Bayanar's tormentor.
Graendal's Guest Edit
Aran'gar and Delana end up hiding out with Graendal. When al'Thor sends Lord Ramshalan to Natrin's Barrow, Graendal, sensing a trap, orders Delana and Aran'gar to place compulsion on him. As Aran'gar announces that she senses a huge amount of the One Power nearby, Graendal realizes it's a trap and shields Aran'gar and Delana so they cannot escape with her. Aran'gar and Delana are burned out of existence along with Graendal's hideout, making the compulsion disappear.
