Not only should they have knowledge about the Holy Sword, as they wielded it against Shinji's group, if I recall correctly from archives provided to me from Kirina, But I also have extensive knowledge on all of them. One of them is a weapons crafter. Her expertise in her field may benefit us greatly.

She performed most of the crafting for our weapon.
