S3E23: a non-stabby family

Well Bambari, this is quite an audacious plan! From what I understand of the weapon in question it is very hard to predict what the outcome will be. I think it depends on the nature of the sword, which we know to be a shard of Ulumbraya’s power significant enough that it had to be taken from her before she could be trapped by the old powers. The question is whether the sword is the power or whether it is a form that the power has been shaped into - in the former case, destroying it would significantly weaken Ulumbraya, but if it is only an embodiment of her power in the physical realm then destroying it may release that power back to her, in which case she could become significantly stronger. I suspect this knowledge lies beyond the mortal realm, so I fear you have little more than your intuition to go on but I have come to believe your intuition is very sound. Even if the lady of the ice is empowered by it’s destruction, it seems she is only one part of the Icewatcher plan so whatever happens would have the potential to destabilise their strategy. Not to mention that you have been tracked half way across the known world in part because you possess the weapon, it might make you far less important in the eyes of our enemy should you relinquish it and much harder to find.
