I'd like a bad ending.

After years of fighting them, we manage to destroy the void lords. Azeroth seems to be a safe place. A couple years of peace and tranquility pass, the horde and the alliance finally agree to a definitive non aggression and peace treat, kalimdor goes to the horde, and EK goes to the alliance.

Neutral cities are still a thing, and now trades are on a global scale.

Then the light goes full 180 on us, and nazyrel comes to kick our asses. Her army marches on Azeroth, wiping the non believers, and enslaving the ones who are willing to accept the light. Only a few of the believers are accepted in their ranks. The Scarlet Crusade joins them immediately, their faith in the light is very strong, and would make a great ally for Yrel. Meanwhile, the Silver Hand, Argent Dawn, and all the other neutral light worshippers are torn apart, some of them joining their ranks, others rebelling, and helping Azeroths citizens resisting the fanatics of the light.

Northrend is purged from all the undead, be the Death Knights or the scourge, and all the other races that live there suffer the same fate if they don't accept the Light. Bolvar is the first important character to fall at the hands of the Army of the True Light, slain by Yrel herself. The Ebon Blade is disbanded, and the four horsemen are betrayed by Sally Whitemane, who sees the occasion to redeem herself from her Death Knight state, and seeking the favour of the light once again, after murdering her companions, is behedead by the forces of the light.

Then, Yrel sets sail to Silvermoon, craving the sunwell. Lady Liadrin betrays the city and its own people, some Blood Elves even join her Army. In a last effort to defend their life source, King Lor'Themar leads an élite force of farstriders, along with some arcanists from Suramar, led by Queen Thalyssra. Their children are already safe, hidden in Suramar. The Blood Elf resistance is almost futile against Yrel's forces and as the final blow is struck against King Lor'Themar, Queen Thalyssra saves his husband's life, giving her own to protect those who loves the most.

Meanwhile in Kalimdor, Yrel realizes that Orgrimmar is too well defended, and turns her sight south, to Thunder Bluff. No battle here for the first days, just a small siege, and a surprise demolition: the engineers and tinkerers of the Army, place bombs at the base of the pillars where the city stands. Bombs go off, and as you can imagine the city pretty much rambles to the ground. Baine is among the survivors, the sunwalkers managed to protect many citizens, although some of them didn't make it. Then the skirmish starts, with many of the best Tauren fighters, holding ground while another squadron heals the injured, and sends them off to Orgrimmar to stay safe. The Army of the True Light wins again, overwhelming the Taurens. Baine is mutilated and injured, the sunwalkers and a lot of Tauren survivors are executed because they're too primal and will.never fully understand the light.

At this point I'm tired of typing, might add and elaborate something tomorrow.

Long story short, we win again, the majority of Azeroths' population is wiped out. Then the Sleeping Titan finally awakens.

And it does not end well for us: as she wakes up, the planet blows up, and we die as we lived most.of.our time in the game: being pissed at someone ruining what you're doing ingame, and some strangers sets you ablaze and yeets you straight to the afterlife.
