He was somewhat arrogant.

History
At Triel, Orthil Voldovan began acting strangely, in Beldimarr's view, speaking stiffly and taking too long to recognize him. Thavaun had magically disguised himself as Orthil Voldovan; Shandril found out about this just as she began her immolation. However, Sharantyr, once she arrived at the caravan, quickly realized it wasn't him.

He was slain by Arauntar in the aftermath of Shandril's immolation.

Rumors & Legends
Somehow, he had been whispered of as far as Scornubel. He was known to the Harpers either in that way or through different means.
