Glamdring

Glamdring, the ancient elven longsword forged in the hidden city of Gondolin and known as the Foe-hammer, emerges as a legendary weapon in Gandalf's arsenal, its slender blade glowing with a cold white or blue light in the presence of orcs. Wielded by the wizard alongside his staff, it proves instrumental in pivotal battles against orcish foes, from the depths of Moria to the defense of Rohan. Throughout the series, Glamdring symbolizes the enduring might of the Elder Days, faithfully serving its bearer through escalating perils without undergoing significant change itself.
