After the completion of Alduin’s Wall, the player can bring followers to Delphine to make them Blades as part of the Rebuilding the Blades quest. This gives these followers Blades Armor. As you recruit more followers into the order, the temple slowly gets upgraded as more people populate the area. After recruiting three blades members, you gain the option to hunt dragons. You speak to Esbern to get the quest to hunt a dragon. You can also gain the Dragonslayer’s Blessing.
