Records regarding the appearance of Tetsuan are scant. Scraps of history imply that she was "plain" in her appearance though exceptionally strong in her ability to channel. She would have praised herself to be the second strongest Aes Sedai since the time of Caraighan Maconar till the arrive of Eldrene who pushed Tetsuan to the third place. Because in TWoTC Caraighan is described at level 3(+10) it can be guessed that Eldrene was at 4(+9) and Tetsuan at 5(+8).
