Squire Asrol is the squire of Sir Vyvin. He managed to lose his master's blurite sword while transporting it from Lumbridge to Falador. The sword in question was a family heirloom, passed down through five generations of Vyvins. Fearing his master's reaction and the ensuing trouble, he begged a passing adventurer to help him, directing them towards Reldo in Varrock for information about the Imcando dwarves. He also told the adventurer where to find a picture of the sword. The adventurer gave him a replacement sword that looked identical, much to his relief.
