Who is Chaos from Stories: All-New Tales and what is their importance?

Chaos is the name given to the shadow men who stalk and absorb those gods who escaped the end of the world and now exist in this aspect. They glide rather than walk with incredible speed and have a rank smell that cannot be mistaken. They have inhuman strength and appear to have no body beneath the clothing they wear. Instead, there is merely a shadow which is the blackness of Chaos. It is a blackness that has no color - a hole which devours all in its path. They are sent by the Shadow - his minions that in another lifetime would be wolves - boxed now in heavy overcoats.
