The Idithuun are a goblin tribe. Like the other goblin tribes, they were called upon by the god Bandos to fight in his name during the God Wars.
Their name, in the ancient goblin tongue, translates to "Goblins of the South".
Trivia
In RuneScape 3, it is suggested that the armour colour Idithuun goblins wear is pink. Although goblins wearing pink goblin mail can be found in the game cache along with the other goblins in the Goblin Temple, they are not actually present ingame.
