A good read to be sure, but it only reaffirms the history of the game itself. The pre-human pre-stygians are literally the giant kings we know of through the game lore, as well as addressed later in the article. The talk of the lemurians overthrowing them was well covered in the game as well, being the downfall of the giant kings and their city. The only interesting thing to note is the tall, pale skinned reference. That would imply that the blood of the giant kings has been cross-bred into the humans, creating the hybrids that make up the stygian royalty as well as individuals such as Tyros, the kinscourge.
