Siegemaster Mar'tak is an orc located at the Iron Bulwark in Hellfire Citadel. She takes part in the Hellfire Assault encounter but flees upon reaching 50% health. She returns in the next encounter directly afterwards as the one piloting the Iron Reaver.
- Howling Axe — Hurls a notched axe at a target, which strikes all marked targets before returning to the caster. Upon impact with each target, inflicts 166250 to 183750 Nature damage to enemies within 8 yards.
- Shockwave — Sends a shockwave in a targeted direction, inflicting 170625 Nature damage and knocking back enemies within 4 yards of each impact.
- Inspiring Presence — Inspires nearby units, increasing damage done by 10%. This value increases while the caster fights enemies.
- She refers to the Iron Horde as the Fel Horde.
- Mar'tak is technically the only boss to take part in two consecutive encounters, other than Deathwing.
- It is unknown what happened to her after the Iron Reaver boss fight. However, despite shouting "EJECT, EJECT!" when the Iron Reaver explodes, the presence of the on the loot table implies she may not have escaped in time to avoid dying.
