Skin-walker

Just remembered this being, possibly the most dangerous NM creature we've ever seen or will see as its a major upgraded version of Songs Powers. Able to use already dead people it takes overs Abilities memories and access to the spell, what's to say that at this very moment that it doesn't have multiple vessels attempting to do the Nightmare Seeds.

We've seen Saints(although exhausted) have trouble taking down Awaken-Ascended Vessels so what will happen while this whole war is going on and thanks to the Soverigns its a good chance to actually take out the waking world by gaining millions of vessels as the only Clan that had saints and could've prevented it was destroyed because of the soverigns and with all the pointless chaos the damned legacy clans mundane followers attacking the government forces, they wouldn't be able to do anything in time if its strikes.

It survived who knows how long in the NM Desert and was able to understand the human language and plan, what's to say whatever the soverigns did its not faking it or just waiting for a opportunity to strike
