Our story begins when the first titan Aman'thul the highfather, awoke from his eternal slumber

For thousands of years, as the Pantheon upheld order across the cosmos and sought out new titans, Sargeras devoted himself to banishing demons to Mar'dum.

He imagined the horrors this dark Titan could bring to the cosmos. A puppet for this void. Corrupting more and more. Could the Pantheon stand against such a being? Why in their eons of searching is this the first Titan they find? How many other dark Titans does this void already have? These thoughts turmoiled in Sargeras' mind.
