Evanellein meets with Elaida and her other supporters to discuss what is going on in the world. She tells Elaida and the others that Amathera has vanished in Tarabon, and that an Aes Sedai may have been involved in the disappearance (TFoH, Prologue).
Evanellein isn't mentioned of Verin's list of Black Ajah members, but she flees the Tower before being asked to reswear the Oaths, making her a likely member of the Black Ajah. Therefore she doesn't get to vote for Egwene as the Amyrlin (TGS, Ch. 46).
"Only a rumor," the Gray sister replied. Her silk dress, matching the fringe on her shawl, was finely cut and scooped low at the neck. Often Elaida thought the woman should have been Green], so concerned was she with her looks and clothes. "Almost everyone in those poor lands is a refugee, including those who might send news. The Panarch Amathera has apparently vanished, and it seems an Aes Sedai may have been involved... " (Evanellein to Elaida; The Fires of Heaven, Prologue).
