Foe-Smiter - This ornate Storm Bolter was wrought by Fedorovich the Great, amongst the foremost weaponsmiths of Mars during the age when the Tech-priests joined with the Emperor's forces to equip his armies for the Great Crusade. It was he who forged so many of the master-crafted weapons still prized by the Imperium today, but even then, the weapon known as Foe-Smiter was considered special. It was presented with honour to the I Legion of the Space Marines, where it was used to great effect by Brother Bartholomew -- the first Grand Master of the Deathwing.
