The Hall of Heorot

bonnzo:

The Ulfberht swords were incredibly rare, insanely strong steel swords that only appeared in Viking Scandinavia from the early 800’s to the mid 1000’s. The Ulfberht swords are normally a thousand times stronger in terms of steel layering and durability than any of the contemporary steel that has been found. As to who or what “Ulfberht” is, no one knows.
