Warmaster Blackhorn

Though once vast in number, only a few dozen twilight dragons now remain. Astride these hardened survivors are the last vestiges of the Twilight's Hammer's army: the elite drake riders of Deathwing's personal escort. Led by the insidious Warmaster Blackhorn, they move with unholy purpose, driven to protect their dark master.
Stage One: Dragonriders, Attack!
Flying alongside the Skyfire and surveying the scene while his massive twilight drake lobs balls of destruction at the gunship, Warmaster Blackhorn gives the order for his elite dragonriders to swoop into battle.
The Skyfire
Sky Captain Swayze helms this massive gunship equipped with numerous cannons and a pair of harpoon guns for its defense. The gunship is sturdy but not indestructible, and if it sustains too much damage the pursuit of Deathwing will come to an untimely end.
Harpoon Guns
Alliance engineers equipped the Skyfire with two repurposed harpoon guns, seized during its prior service in Northrend. Harpoon gunners spear the enemy's Assault Drakes and reel them in to bring them within reach of ranged attackers on the deck. The drakes strain against the line, eventually breaking free and returning to a safe distance. After a pause to reload, the harpoon gunners then spear their target anew.
Goriona
Warmaster Blackhorn takes to the skies with this massive twilight drake.
Twilight Onslaught
Goriona unleashes a massive blast of dark energy at a random location on the deck of the Skyfire. Twilight Onslaught inflicts %106401s1 Shadow damage, divided evenly among all players within its 10 yard radius and the Skyfire. If the attack strikes the deck of the Skyfire without hitting a player, the gunship suffers the full damage.
Twilight Assault Drake
These drakes strafe across the deck of the ship, deposit their fierce riders onto the deck, and then retreat to a safe distance to bombard the gunship.
Twilight Barrage
The twilight drakes launch bursts of dark energy at a random location on the deck of the Skyfire. Twilight Barrage inflicts %107439s1 Shadow damage, divided evenly among all players within its 5 yard radius. If the attack strikes the deck of the Skyfire without hitting a player, the gunship suffers the full damage instead.On Heroic Difficulty, Twilight Barrage also increases Shadow damage taken by 140000% for 0 sec.

The Dreadblade carves a swath of destruction with its dark sword. The sword inflicts %107558s1 Shadow damage to enemies in a frontal cone, and %107558s2 Shadow damage every 2 sec for 1 min. This effect stacks.
Twilight Elite Slayer

Twilight Sapper
Sleek infiltrator drakes airdrop goblins strapped with powerful explosives onto the deck of the ship. These Sappers rush to breach the gunship bridge and detonate their destructive payload.
Detonate
Upon reaching the Skyfire's bridge, the Sapper detonates his explosives. The blast inflicts %107518s1 Fire damage to players within 8 yards, damages the Skyfire for 20% of its total durability, and kills the Sapper.
Stage Two: Looks Like I'm Doing This Myself
Once the Skyfire's defenders defeat three waves of dragonriders, Warmaster Blackhorn leaps down onto the deck of the gunship.

Vengeance
As Warmaster Blackhorn takes damage during the course of the fight, he inflicts 1% more damage for each percentage of his missing health.
Goriona
After depositing her master on the deck of the Skyfire, Goriona hovers alongside the Skyfire and rains destruction down on the players. Once Goriona has suffered sufficient damage, she will break off and flee, abandoning her master on the Skyfire.On Heroic mode, upon reaching 90% health, Goriona will land on the Skyfire's deck to assist her master.
