The Twin Swords of the North

Two identical artifact longswords, that according to the legend once were wielded by the twins Shek and Elkal. The brothers were barbarians similar to present-day Vikings. The two brothers were invincible when using the swords, and the swords were buried along with the twins. According to the legend, the two swords will reappear if Middle Earth is in peril, and two realms of the north are governed by two person descending from Shek and Elkal respectively. Sages used to believe that the two realms would be the Djugosir and the Varnasir, but in the time of the Troll Wars the prophecy was used to argue that Uchard Corvendil should be the king of Falandria, as the Corvendil and the Storlad families are related.
