Imsha was a sorceress and cleric of Chauntea and a Hathran of the Witches of Rashemen. In death, her spirit became one of two telthors tied to the Red Tree, a legendary aspen tree located within the Immil Vale in Rashemen, by 1372 DR.

She and the other telthor, Tamlith, provided wisdom and guidance to the living witches of Rashemen. They talked only of important matters, especially the security of Rashemen, and didn't like idle chatter.[1]
