when are we going to find out what the other sword is? it seemed to be a bronze sword and although they said talk to the Norse I think it could be from the Greek, Egyptian, or Babylonian which are all bronze age civilizations, maybe the sword of Troy or something.
Definitely celtic. At first I thought Sword of the Siegfried or something from Nibelung which happened at the migration period, but as it seems to be made of totally bronze, it is over thousand years older. Then I checked some legendary celtic swords and got some names from the legends of Tuatha de Danann and such. Of those my guess would be:
Díoltach (Retaliator), one of the three main swords of the sea-god Manannán mac Lir. The sword that “never failed to slay”
I would be poetic that our hero wielded sword of peace on the other hand and sword of the retaliation on the other hand.
Btw. The name of Durendal bothered me as I had always thought it to be Durandal, but apparently they're both valid spellings.
ps. Which one of you did it? " A replica sword that was embedded in a rock face there was reported stolen in June 2024."
