Druinval

Druinval is a sword that first appears in The Iron Prison by Sam Ruby and is best known as one of the four weapons normally carried by the adventurer Sam.

The sword originates in Middle-earth and is given as a gift to the adventurer by the powerful Valar as a reward for successfully completing the adventure. It's forged by the Valar smith Aule who crafts it from mithril. Ruby describes it as a sword of great beauty that emits a red glow, and notes that its name means "Flame of Might".
