Tyr's Hand Abbey is the smaller of the two religious facilities at Tyr's Hand, the larger being the Scarlet Basilica. The abbey is well tended for, and has different function for the religious Scarlet Crusade than the basilica does. It is built very much like Northshire Abbey, comprised of three sections named the Main Hall, the Hall of Arms, and the Library Wing.

Blood Knights seeking to obtain the rank of Master and ride the Thalassian charger must enter the Abbey, obtain a vial of its holy water and bring it back to Lord Solanar Bloodwrath in Silvermoon.
