Skardyn are an allied race affiliated with the Horde.
Near the end of the War of the Three Hammers, most of the Dark Irons fled towards their home city, but as the Wildhammer army pursued the main force, some of the Dark Irons instead fled into Grim Batol. The descendants of these Dark Irons were transformed into Skardyn inside Grim Batol, ironically caused by the curse of their ancestors' sorceress queen.
