... Unfortunately, the statues broke down. Much of the lore of the Golem Crafters was forgotten, until the Ktonian Necromancers came, and the Agarthans themselves could be reanimated... "as guardians or company".
The ancient race, the long-gone, was never forgotten. I find the concept of Agartha touching - it's one of the only races where humans and non-humans live side-by-side, respecting each other, only for the ancient ones to die. Even in death, they are respected, the tombs taken care of, the bodies reanimated to tell of the old times.
