In the Grimoire of the Shadow Lands, it is said that the First created the Pantheons as the embodiment of the influence of their cosmic forces. And so, an important question. Why didn't the Titans mention the First Ones in the Chronicle? Yes, I know that in those days the Chronicles were not the opinion of the Titans, and the First Ones had not yet been invented, but this is just a huge plot hole. The Titans seem to be unaware of the First Ones. Compare Titans and Eternal Ones. The Eternal Ones respect the First Ones, and the Jailer despises them, considers the universe imperfect, and wants their power. The Titans never mentioned them. For example, Sargeras did not wonder why the First Ones allow such an abomination as the Void Lords to exist.
