The Summer Sword

The Summer Sword is a very large and powerful two-handed greatsword. It was won by Loghain Mac Tir from its previous Orlesian owner - Luis, son of Lord Aurelien of Montsimmard. Loghain perhaps lent or gifted it to Ser Cauthrien, the commander of his elite soldiers.

Trivia

 * It is possible to obtain two copies of this sword. If you kill Ser Cauthrien and loot her during the Rescue the Queen quest, and then allow the remainder of her guards to kill your party and capture the main player and Alistair, she will respawn and confront you at the Landsmeet.  Both times she will have the sword on her body.
 * If you defeat Ser Cauthrien in your first encounter at the Arl of Denerim's estate, it will also have the chance to knock an enemy back.
