But are the Titans dead? My own theory, to borrow a line from a famous philosopher, is the Titans are only dead “from a certain point of view”.
A simplified story
I think we’ve received a simplified version of the story; the same way a wise parent will simplify a horrific story for a child too young to comprehend it. We know that when the Titans died their essence came to Azeroth and inhabited the Keepers. Only Keeper Ra understood what had happened and it sent him into a deep malaise. The other Keepers couldn’t even process it.
But could being as colossal as a Titan’s have their entire essence housed in a Keeper? I think not. We are talking about the beings of such enormous size and power that they killed an Old God like we might swat a mosquito. Not all their essence went into the Keepers. It couldn’t have. I think some of the Titan’s power infused into the planet itself and from there into its inhabitants, and it might have been Amun’thul’s plan all along.
We know the Titans scoured the universe for sleeping world souls. Like Sylvanas, they realized they had no way to produce more of their kind. They even called Azeroth “the Final Titan”. At that point, Amun’thul must have realized there would be no more Titans.
We are told that in the final battle with Sargeras, Norgannon wove a spell just before the Titans were destroyed. I don’t think Norgannon came up with that in the spur of the moment. A spell that powerful must have been prepared. We’ve seen from the Forge of Origination that the Titans loved fail safes and Azeroth itself may have been a final fail-safe for the Titans. Amun-Thul knew there was a real chance Sargeras would defeat them, and if he did, it would mean the entirety of Pantheon wasn’t enough. To save creation, they needed a larger, more powerful Pantheon. But Azeroth was the last world soul. There would be no more Titans, no additions to the Pantheon. The fundamental problem still existed.
How do you make new Titans?
Before their battle with Sargeras, Amun’thul worked with Nargannon to create a way to send the Titans essences to Azeroth. If the Pantheon defeated Sargeras, they won. If Sargeras defeated the Pantheon, he wouldn’t kill the Titans, he would free their essence to inhabit and power an army of heroes creating a new pantheon larger and more powerful than the first and one capable of defeating Sargeras once and for all.
The champions and heroes of Azeroth are the reincarnation of the Titans.
This is like the concept of the Bhaalspawn from Baldur's Gate. Spoiler alert for an 18 year old game but your character and all the enhanced individuals in Baldur's Gate are Bhaalspawn -- the mortal offspring of the now dead god Bhaal and females of various races.
We aren't the mortal offspring of the dead Titans but in the same way that Bhaal spread his ... err.. essence into Abeir-Toril, when the Titans died, their essence spread into Azeroth. Over time it coalesced in certain individuals. Sometimes it found a compatible spirit with a Titan forged like the Dwarf or Gnome. Other times it found a receptive host in a native being like an Elf or Troll. Even sentients from others worlds like the Draenei and Orcs possessed compatible spirits.
These Titan essences are what set our characters apart from the other ‘normal’ individuals on Azeroth. From our first adventures, we have been working to continue to better harness that Titan power within us, getting stronger and more powerful with each passing day.
Each Titan essence gives the hero a bent towards particular powers. Those who have the essence of Eonar the Lifebinder become Holy Paladins, Disc/Holy Priests, Resto Druids, and Mistweavers. Norgannon’s spirit gave rise to all Mages, and Balance Druids. Khaz’goroth and Aggramar’s essence leads the adventure to becoming a physical DPS or tank. I couldn’t decide which one would fit. I think tanks fit Aggramar given his Pillar, but Prot Warriors carry a scale of Neltharion whose power came from Khaz'goroth. Golganneth’s essence powers all Shaman. Aman-Thul, like his Keeper Odyn, is the all father and all of Azeroth’s champions carry a tiny spark of him in them.
The Titan’s aren’t dead
They live on in each of us, and through us, they will again face off against their wayward brother Sargeras. Only this time, instead of five Titans, it will be an army of Azeroth’s mightiest heroes, and when that happens, Sargeras will fall.
