When Paitar went to the Black Hills, to the meeting with the other King and Queens of the Borderland Nations, he brought Coladara with him, as well as seven other Aes Sedai that were with her. Speaking about Coladara, Paitar seems quite fond of her. When Queen Tenobia hears mentions of Aes Sedai she announces that she has also brought five Aes Sedai whom she ran into before leaving Saldaea.
Coladara probably was in Braem Wood when Elayne met the Borderland rulers there. Preparing the meeting Merilille told her about the presence of some sisters with the Borderlanders, but Elayne did not meet any of them personally.
Coladara probably was in Far Madding at the meeting between the Borderland rulers and the Dragon Reborn. There Cadsuane wants to meet the thirteen Aes Sedai that are accompanying the Borderlanders.
At the Last Battle Coladara fights in the Shienar with the Borderlander armies; she goes because she insists on staying with King Paitar as his advisor.
