Story Spoilers: Nyarlathotep?

[Alardem]

Funnily enough, the Amnesia fan wiki's detailed breakdown on the Shadow paints it as an almost anti-heroic force which only torments Daniel in order to help it stop Alexander.

Why is it that Mandus is not also hounded by some supernatural guardian of the Stone Egg? Does that indicate the Egg has a different function/purpose from the Orbs used by Alexander? I personally want to think that whatever Mandus discovered in the Aztec temples is unrelated to the artifact that Daniel discovered, since unfamiliarity and unpredictability are a hallmark of cosmic horror.
