Is Manus the Furtive Pygmy?

Manus is the "Father of the Abyss," so he created the abyss. The Furtive Pygmy was the owner of the Dark Soul, and unleashed it when the fire began to fade. If the first appearance of the abyss was in AotA (because of Manus), doesn't that make Manus the Furtive Pygmy?

Also note that both were human. AND in the Chasm of the Abyss, we see a bunch of splintered humanity, and we know that the Furtive Pygmy split the Dark Soul for humans.

Thoughts?
