Lasaraleen Tarkheena

Tarkheena Lasaraleen was a Calormene during the Golden Age of Narnia, and a childhood friend of Aravis. Lasaraleen was the wife of a rich and respected Calormene Tarkaan, and lived in the Tisroc's palace. She is described as annoying and a "terrible giggler", always gossiping about weddings, engagments, parties, and scandals. Yet, despite this, she assisted Aravis during her escape from Calormen by hiding her and smuggling her out of Tashbaan.

In The Horse and His Boy, when Aravis and her fellow fugitives are trying to travel unnoticed through Tashbaan, she is recognised on the street by Lasaraleen. To keep her quiet, Aravis jumps into her palanquin and asks her old friend for help, and Lasaraleen smuggles her into the Tisroc's Palace. Lasaraleen doesn't understand why her friend wants to pass up marriage to the Grand Vizier and a life of wealth in the Palace to go to the 'barbarous' country of Narnia. But at Aravis' request she has her servants care for the two talking horses and take them and Aravis to the Tombs of the Ancient Kings outside Tashbaan, where Aravis has arranged to meet Shasta.

While the girls are sneaking around the palace at night, they overhear a secret conversation between the Tisroc and Prince Rabadash, in which they find out about Rabadash's plan to invade Archenland. The scared Lasaraleen panics and almost reveals their presence, which would have resulted in their being put to death.
