Template:Mobbox The Seven were dark iron dwarves of great knowledge and power. It is likely that they were the ones who, along with Emperor Thaurissan, summoned Ragnaros the Fire Lord to Azeroth.
In Alphabetic order (not the order you fight them), they are:
- Anger'rel: casts Strike (increases the caster's next melee attack), Shield Black,
[Sunder Armor] - Doom'rel: casts Summon Voidwalkers (summons three Voidwalkers),
[Curse of Weakness], 
[Demon Armor], 
[Immolate], Shadowbolt Volley(targets everyone within 30 yards in front of the caster) - Dope'rel: casts [Sinister Strike], [Backstab], [Gouge]
- Gloom'rel: casts [Cleave], [Hamstring], [Mortal Strike]
- Hate'rel: casts Strike, Shadowbolt, [Mana Burn], Shadow Shield(shields a set amount of damage and deals shadow damage to melee attackers)
- Seeth'rel:casts [Blizzard], [Frostbolt], [Frost Nova], [Frost Ward], [Frost Armor]
- Vile'rel: casts [Heal], [Prayer of Healing], [Power Word: Shield], [Mind Blast]
Upon their defeat, the Chest of The Seven is lootable.
