Tarntassa's Tower was a mage's tower in the city of Tantras in the Vast, standing off Sandril's Lane in the western side of the city. It was the home the adventurer-mage Tarntassa.[1][2][3]

Tarntassa was a friend to the Harpers. Harper agents were welcome at her tower, provided they came quietly under cover of dark.[1]
