In His House He Waits Dreaming.

They freed the final two watchers; Hodir and Mimiron, before Thorim re-joined them as the doors to Yogg Saron's prison opened before them.

"We will aid you as best we can, but the horrors it will unleash you must face alone." Thorim informed them as they moved towards the open door.

"We appreciate any assistance you can give noble watchers," Alexstrasza bowed, before the four watchers teleported away.

"What horrors?" Alleria asked, sounding slightly worried.

"Whatever it throws at us, we'll face it together and win," Sylvanas said boldly.

"You ever faced an Old God before?" Alleria asked as they moved through the shattered hallways, the sense of dread getting stronger the further down they went.

"We... I've faced their minion and followers in the past year or two, but never an actual Old God," Sylvanas replied. "Though we did defeat an Elemental Lord!"

"The elemental lords were pawns of the Old Gods before the Titans came to bring order to Azeroth," Alexstrasza informed them. "I fear this threat will truly test your skills and resolve."

Having just mentioned the pawns of the Old Gods, they were hardly surprised to find a large antechamber filled with the vile creatures. Alleria quickly fired a volley of arrows into the oncoming minions, picking off the weaker ones and enraging the others.

"You will not stop the Old God's return!" they yelled.

"Just try and stop us!" Alleria mocked, as Sylvanas cut them down with ease.

Just as they were dispatching the last few minions, the doors on the far side opened, and a large faceless creature stomped into the room, blocking their path.

"Your destruction will herald a new age of suffering!" the abomination roared, before charging towards them.

"I will not allow that to happen!" Alexstrasza roared back.

The Dragon Queen transformed into her natural form and breathed fire at the faceless one, the abomination immediately screaming as it was burned.

"That was too easy!" Vereesa noted.

"It's master will not be so easy," Alexstrasza noted. "I can feel it in my mind, trying to sow doubt and fear about our mission."

"Are you capable of continuing? We must be close to Yogg Saron for it to be affecting you so strongly." Sylvanas noted.

"Do you feel up to facing an Old God alone?" Alexstrasza asked, one hand massaging her scalp as the whispers grew more numerous.

"Ahem!" Brann's voice came over the communicator. "I might have a little support for ye."

On cue a long procession of Iron Vrykul and Dwarves, and two Iron Giants came marching down the hallway behind them.

"I think these will help, thanks Brann" Vereesa commented.

"Not a problem lass, give that God a good thrashin' for me," Brann's voice said proudly. "I'll continue monitoring the construction of more Iron constructs, they should..."

"Brann?" Vereesa asked after he cut out mid-sentence.

"Maybe the Old God is messing with it, we should hurry!" Alleria said quickly.

"Are you coming my queen?" Sylvanas asked.

"The whispers... They're relentless," Alexstrasza said in a low voice.

"We should return to the Conservatory until the God is defeated, before we succumb to the madness," Ysera said, ushering her sister back up the hallway.

"I'm sorry Windrunners, you will have to face the Old God without us," Alexstrasza apologised.

"Ysondre? Onyxia? Are you able to help us?" Alleria asked quickly.

"Yes, Malfurion's mental protection is still in place." Ysondre explained. "I can still feel the whispers, but they are like scratches against glass."

"I wish you luck my dears, and I grant you my blessing, may it give you strength against the Old God's manipulations." Alexstrasza said, before her, Ysera and Kalecgos hurried back up to the surface.

"How bad could it be?" Alleria said, seeing the small army of Iron constructs awaiting their orders. "Move out!"

They followed the dwarves down another shattered corridor, where the damage was far worse than the previous corridor.

"Maybe we can use this damage to bury the Old God after we beat it!" Alleria noted.

"These Iron Giants will certainly make that a possibility." Sylvanas added.

They reached a large, reinforced door, and knew that the evil they were facing lay on the other side.

"This is it," Sylvanas breathed as she unsheathed her swords. "Be ready for anything, don't listen to its whispers, and do not give into fear or doubt... We can do this."

"I'm with you sister," Vereesa smiled, rolling her shoulders and summoning a water elemental at her side.

"This is just the beginning, a stepping stone to stopping the Legion," Alleria added. "Let's do it!"

The doors opened as they drew closer, and what lay on the other side surprised the three Windrunners. A lone female Vrykul was being slowly advanced upon by hordes of Faceless ones, but what perplexed Sylvanas was the lack of any damage to the room, or sign of the Watchers who had promised to help them.

"Let's kill the bastards!" Alleria said, beginning to move forward, but Sylvanas stopped them and the small army accompanying them.

"Wait... This isn't right," Sylvanas noted.

"Heroes! Help me!" the woman yelled when she spotted them.

"We should save her!" Vereesa said urgently.

"I don't think she needs our help," Sylvanas replied. "Alleria, lend me your bow."

Sylvanas took Alleria's bow and a single arrow, nocked it and aimed it at the woman.

"What are you doing?" Alleria hissed.

"Light, illuminate the truth and wash away the darkness that blinds us," Sylvanas muttered, as the arrow began to glow.

She released the arrow and suddenly Alleria and Vereesa understood their sister's hesitance. The arrow hit the woman in the chest, and the second it hit the Faceless ones stopped advancing on her. As the woman began to laugh, her voice echoing around the chamber, the true prison cell revealed itself. Shattered glowing chains and a cracked stone floor appeared as an invisible fog faded around them; revealing. much to their relief, the Watchers were standing on four pedestals around the edge of the room.

"I am the lucid dream, the monster in your nightmares, the fiend of a thousand faces." The woman said, her voice becoming more monstrous and deeper in resonance.

"We really should listen to you more," Alleria breathed.

"Cower before my true form," the woman said before she sank into the inky blue water. "BOW DOWN BEFORE THE GOD OF DEATH!"

"Attack!" Alleria yelled, as Yogg Saron revealed itself.

The God of Death was truly monstrous in its true form, a large curved head with a gaping maw, with its eyes being smaller gaping mouths.

"Focus on its tentacles!" Vereesa ordered, as one of her spells was deflected by a shield protecting the Old God.

Sylvanas followed a small group of Iron dwarves toward one of the larger tentacles, wheeling her head around at a loud bang, the two Iron Giants had been locked out, but the echoing bangs told her they were still trying to get in. As the tentacles sunk into the floor after being severely wounded, more sprouted up through the cracked floor, and minions of the Old God spawned through portals appearing with equal regularity.

"Heroes, find solace in Eonar's light, let it protect you from the Old God's madness!" Freya called.

"What the hell does that mean?" Alleria yelled.

"Step into the beams of light for a respite from its whispers," Vereesa called, Sylvanas glanced over to see Vereesa was standing in one of the three beams of light.

They continued to fight and dispatch the tentacles and minions until Sylvanas heard a scream. She looked around and noticed Vereesa had vanished, but before she could raise the alarm; her sister reappeared a short distance away.

"Where did you go?" Alleria called.

"I don't know, I saw a vision of the past," Vereesa replied, hurrying to a beam of light for protection. "I saw the creation of the Dragon Soul."

"Makes sense, Deathwing was being influenced by the Old Gods," Onyxia called, moving to fight beside Alleria.

"Why would it show us that? It's ancient history!" Ysondre asked, hitting multiple minions with lightning.

"To demoralise us? To confuse us? It's not going to work!" Alleria laughed, before she was sucked into a portal.

"He's targeting us!" Vereesa called, before Alleria returned close to Sylvanas.

"What did you see?"

"That Orc bitch killing King Llane!" Alleria spat.

"That's more recent, which means..." Sylvanas commented, before everything went momentarily black.

She looked around and shuddered as she saw a familiar form standing before a large winged demon.

"Kil'Jaeden is displeased with your progress Ner'zhul," the demon said calmly, and Sylvanas moved closer to watch the Lich King's reactions.

"I have weakened this world for his invasion, doubt has been sown throughout the Alliance, and the mighty Dragonflights have been scattered to the winds," The Lich said proudly. "All I need now is an artefact of power to open the way for his invasion."

The demon grinned menacingly.

"Kil'jaeden knows puny wretch," The demon chuckled, withdrawing something from its belt. "Consider this a gift. Use it to fulfil your purpose, or face his eternal wrath."

The Lich took the object and looked at it, before the demon disappeared in a ball of flame. The Lich looked agaub at the skull in his hands and laughed.

"Oh how the times have changed," The Lich chuckled. "Isn't that right, Gul'dan."

Sylvanas roared in anger, and stabbed the illusion of the Lich King. The second her swords touched the illusion, there was a deafening roar and the environment around her shifted. She was now standing in a claustrophobic dark chamber, with a pulsing organ above her. She wasn't sure why, but she felt compelled to attack it. She slashed both swords across the pulsing organ, before dropping to her knees as another scream deafened her. Before she could get to her feet and cause the Old God further pain, she and her weapons were spat out of one of the God's many mouths.

"Look upon the true face of death and know that your end comes soon!" Yogg Saron boomed, as more tentacles and minions spawned, but the shield protecting the Old God vanished.

"Focus your attacks on it! Let's finish it!" Alleria yelled to the few surviving Iron constructs.

The tentacles destroyed the last constructs, as they moved to attack Yogg Saron, The heroes skilfully evaded the flailing limbs, responding by landing several attacks against the Old God.

"Onyxia! Ysondre! Finish this!" Alleria yelled as the Old God emitted a deafening roar.

"Eternal suffering awaits!"

Ysondre summoned a vast cloud over the Old God, before she and Onyxia breathed fire at Yogg Saron. The Old God screamed in agony, the tentacles flailing wildly as they were struck by lightning, before one-by-one retreating into the floor.

"Your fate is sealed. The end of days is finally upon you and ALL who inhabit this miserable little seedling." Yogg Saron bellowed, as it sunk beneath the inky blue water. "Uulwi ifis halahs gag erh'ongg w'ssh."

"Is it done?" Alleria gasped, almost collapsing from exhaustion.

"You have not killed it heroes, but you have weakened it again, it will take several centuries for it to rise again." Thorim told them as the four Watchers leapt down from their podiums. "We thank you for stopping its corruption before it spread beyond Ulduar."

Hodir quickly turned the water to ice, and Mimiron quickly began repairing the broken chains around the edge of the room.

"Wait... We killed the Prime Designate, will the Pantheon initiate planetary re-origination?" Vereesa remembered.

"The Pantheon will send an agent to determine whether or not re-origination is required," Freya explained.

"When would they arrive?" Ysondre asked.
