I’m of two minds when it comes to the Arathai situation.
The Empire itself is obviously going to be an enemy, or at best a rival, to both the Horde and Alliance given what Faerin admits about them being less than tolerant of the other races, and even NPCs talking about putting down uprisings and their fanaticism about the Holy Flame, but I think the story is going to play out in one of two ways.
- Disney Vision Arathai Empire
Emperors tend to be above Kings and also tend to have ‘Divine Mandate’ behind them, at least in modern fiction. The Arathai Emperor is going to be entirely down to clown with the fanaticism and bias and it will be a standard “Overthrow the people gone mad with power” story-line with rebellious or conscientious objectors within the Empire, both amongst the nobility and the common/subjugated people/races helping us pull this off.
There’s also the issue that the Holy Flame isn’t pure Light. Fire must consume to sustain itself, and we see this aspect in the zealotry of the more hardline Arathai, and the traditions of burning the remains of the dead, and their belongings, as an offering to the Holy Flame. Everything must be given to the Holy Flame as thanks for its guidance and protection, no matter what. We’ve seen Elementals like Ragnaros and Neptulon aren’t strictly ‘pure’ like they claim to be. Ragnaros has magma aspects to his body, which is molten rock, and Neptulon has organic matter as well as air currents surrounding him. Dual-nature and even Para-mental Elementals have existed since Vanilla, and we’ve seen Fel-infused Fire and Earth elementals, Light elementals and even Void-infused Elementals. We know that where-ever the Arathai Empire is, it is located on the opposite side of the world, on the other side of this ‘impassable’ barrier where the Titans either did not or could not spread their influence. If Azeroth was truly under the domination of the Black Empire, did that mean that the other side of the planet was under the control of a Light-based Empire ruled by Naaru or other Light-aligned or -adjacent entities? Is there Light-Forged or -Bound Elemental Lords over there, either willing or unwilling, who aided these entities?
We know that Naaru will decay and fall to Void the longer they are around Mortals, so leaving proxies via Elementals, native to Azeroth and capable of reviving over and over again, now empowered and bound to the Light, to act as avatars of the Light’s will to the mortals who served and aided this Empire?
It may be, because the Light is of ‘Order’, that the Titans didn’t oppose this Empire because it was within their parameters for Azeroth’s function and they either didn’t want to, or couldn’t afford to, fight the Light in addition to the Fel with Sargeras off and refusing to answer his phone, or perhaps some sort of divine politics were involved? Either way, the barrier of storms and waves that destroy all passage to the other side of the planet might be a Titanic construct intended to keep the Old Gods and whatever Void-tainted remnants of the Black Empire contained to this part of the world, where the Titan Keepers and Watchers could deal with them, rather than risk the other, untainted side of Azeroth being infected with ‘Chaos’, be it from the Void or other Primal Powers.
- Subverting Expectations Arathai Empire
The Emperor is a puppet of those who rule the various ‘sectors’ of the government, a true Prophet of the Holy Flame but one whose ability to influence their own Empire is harshly constrained because it does not fit the agenda and narrative that their Generals, Nobles and High Priests wanted, and this quasi-immortal Emperor (Or Empress … we don’t know if the Emperor is one person, or a succession of those who are annointed by the Holy Flame and given prophetic powers as a result) is locked up in their big fancy castle … and milked for prophecies and visions, and held in check with the threat of purges and other horrific acts that will be explained to the people as The Emperor’s Direct Command if they don’t play along with their captors’ goals.
In this case, the Emperor is going along because its the least vile of the options on the table and so long as they do, there’s a chance that they can break free somehow and actually steer the Empire in the direction it was always meant to go before self-interest and bigotry twisted the Empire off-target. It would explain why the force we encounter in Hallowfall is the way it is, because the Emperor (or Empress …) received a vision that gave them hope that this horrible status quo could be broken and they very carefully nudged enough people who would be able to reach the goal into the expeditionary/scouting force and contact us, the only other forces on the planet that could not only defeat the Arathai Empire, but also save what’s left and help them get back onto their feet, and the correct path that the Holy Flame was guiding them towards.
And the entire armada was teleported to the region. Either that giant crystal did it … or the Emperor did, knowing that, at the time of their arrival, they’d destabilize the Horde and Alliance and hinder us more than help. But now, in their current state, they’re no threat to us, we can prove our use to the Empire and make (at least at first) positive first contact with the Empire and its de-facto leaders before things start to go sour, so we’ll have at least a toehold to launch an invasion, or counter any subjugation attempts by the Empire itself.
Or I could be pushing hot air out the wrong set of cheeks again.
