The Abbey of the Just Hammer was an abbey in Tasseldale, in the Dalelands, dedicated to Tyr. It was positioned close to the River Ashaba. The abbey's focus was upon the justice element of Tyr's portfolio and provided legal education for free. As of 1372 DR, the Abbey lacked numbers due to the drow threat in the north. On 22 Mirtul 1373 DR, the Abbey was attacked by the green dragon Sirvinhandra, who was defeated by Lord High Justiciar High Avenger Deren Eriach.
