Alternate Earth Campaign
Prince Thrommel's Sword
Ancient Tuathan/Vaniir sword
This is a seemingly celtic/norse bastard sword made of some metal far stronger and lighter than steel. It is very fast and has been known to cut through armor and shields with ease.
It is not generally known where this blade came from, only that Prince Thrommel began using it in the middle of the war with the temple and that it was believed to have been instrumental in turning the tide.
