Duke Zalto is the ruler of the fire giants in Ironslag.
 
Zalto is one of the giant lords at time of the shattering of the ordning. In 1491 DR after the disappearance of the storm giant king Hekaton, all of the giant lords took to reshape the ordning to their own fitting. Zalto first led his minions to reclaim Ironslag in the North Faerûn, the greatest forge of ancient Ostoria, planning to reconstruct the ancient colossus construct Vonindod, a relic of the Thousand Year War, and unleash it upon the hated dragons.
