How do the fallen usually deal with the swords? Alot of it is running right. It takes a specific act to break the power of a sword, what if this blade can be used to meet one of the swords? The sword allows a mortal to fight creatures more powerful on a even battle field. THe sword might undo that.

 The blade might potentially allow unbound fallen a way to influence the world. THe swords each seem to have an archangel as their patron. Imagine such a blade used by a denarian host.

 The swords allow angels to interfere without the fallen being allowed to act as well. A blade of the fallen would allow them to act more freely than before.

That blade has serious potential, I bet it allows the power of hell to act on earth, like the sword do for heaven, or at least potentially, hopefully it could become the 4th sword of the cross.

i think hellfire was used to make the circle used too deal with the archive by the fallen.

the swords of the cross comes with restrictions correct, it was why murphy could not harm nic that time. would the hellsword have it own restrictions that can be used against it?

 What if a magical sword similar to warden swords was made? Posibly made with the use of soul fire, or the potential to use soulire, to channel great power against their enemies.

 As an oath breaker to the accords, this allow mab and other to act against him correct. Summer and winter working together to really mess the denarains up. Usually, they need a connection to interfere, but the accords will suffice. If no longer accord members, then those that are can act with out consequences towards them.
