Black and Purple
"A kindred spirit...I did not think such a thing was possible."
"You'll be surprised..."
Deathwing, a.k.a. the Destroyer, a.k.a. Neltharion, a.k.a...well, there were many names he could use, most of them obsolete. Either way, he smiled, his teeth barred to the extent that only a fraction of his inner fire shone out. He did not know what to make of this purple dragon before him, a colour only possessed by some nether dragons. Still, it seemed this...Regulos was not of the Outland-spawned flight. And that made him all the more curious.
"Your world..." the former Earth-Warder asked. "It is named Telara?"
"Was..." the purple dragon snarled. "But soon it will be mine...ours...the Blood Storm's..."
"Blood Storm?"
"An ancient order of gods. Served by the Dragon Cult"
Deathwing sniffed the air, steam billowing out like a dwarven steam tank. An ancient order of gods? It reminded him of the fabled Old Gods of Azeroth, though he was not sure why-probably some of that nonsense spurted out by the Twilight's Hammer Clan. And speaking of the Twilight's Hammer...this Dragon Cult...they sounded similar, seemed to act similar...it seemed that he and Regulos had not only be wronged by their respective worlds, but had sought vengeance simultaneously, within months. What were the odds?
"But Telara will be mine. I will undo the work of the Vigil gods. The world has been torn asunder, and its fall is inevitable."
"...funny. I thought the same thing as soon as I emerged from Deephelm.
Regulos remained silent, seemingly caught up in muttering about his plans. Plans, Deathwing noticed, seemed remarkably similar to his own. Banished from the world? Check. Cult of followers? Check. Plan to shatter the world? Check. Plan to conquer/reshape the world? Check. Plan to defy the work done by a race of powerful beings? Well...he had said "gods" rather than "titans," but...well, that was a check as far as the leader of the Black Dragonflight was concerned. So yes, their plans were practically identical. Their species was identical. Heck, if it wasn't for this purple dragon being...well, purple, Deathwing half suspected they'd look similar as well.
This is...strange. Now Alextraza's kind of strange, not even the strangeness of a mortal's feeble mind...Two dragons, carrying out the same plan at the same time? Different worlds, true, but all worlds are connected through the Twisting Nether. The planes of...wait a minute...
Deathwing smiled again. It seemed petty, but he wanted to be different from this... "Regulos," to assert his own identity. He had the feeling of being...older, more...established than his counterpart, but even so, he wanted to prove it. And to do that, all it would take was a simple mention of his plans.
"Well, I should go..." the black dragon mused. "I have torn a rift between Azeroth and the Elemental Plane. I think it's time I widened the wound."
Regulos nodded in understanding. "Indeed, a worthy plan. Almost as good as my own."
"...what?"
"Oh yes. Open the Plane of Death, watch it seep over...one of many elemental planes of my own."
"What type of planes?"
"Oh, the usual. "Earth, air, fire, water..."
"...funny, Azeroth's elemental plane corresponds to the same elements."
Funny...it wasn't funny at all. This was...was...heck, Deathwing didn't even know what it was. It seemed ridiculous, but it was if this Regulos and everything about him had been built in his own image.
Suddenly doing the same for Azeroth didn't seem so appealing...
A/N
Yet another Rift/Warcraft crossover, though this time focussing on Deathwing and Regulos specifically. After all, when you use a summary of their goals and interchange "gods" and "titans," they're pretty much identical.
