How does the Council assign Watchers to people who aren't contracted with them? If they can do that, why don't they just give Watchers to the super strong guys who are in charge of the armies and have them fix it? Why don't they just give a Watcher to Sevrin and tell him to stop making the apocalypse happen?
Why are they asking our group to help at all when they have the four horsemen to fix things? Or barring those guys, they can just give a Watcher to Nero, who's more than proved himself as capable after DMC4.

What's our group's incentive to fix things, beyond 'several of you failed once and it's all your fault because of it'? Several of us weren't even there; therefore it couldn't be our fault. Furthermore, how can you motivate players or characters without loot? Keep in mind half the players are mercenaries of some kind.

Isn't there a more fluid and natural way to give your players than literally telling them "Do what we say or die"?

I'm glad I have a friend looking out for me.

The Watchers cannot be technically bound to a being that is not contracted, and they cannot close their eyes and think "I'm going to appear wherever X is" and then do so.  In the case of all these characters, the were sent to find them, manually found them as they left the Eidolic Cairn in various ways.  Sevrin, Gomory, and the rest who left by other means obviously can't be tracked in this manner.  The Watchers cannot enter Heaven or Hell, and so cannot even come close to influencing the beings there.  

The Horsemen can only be summoned to Earth after the breaking of the seventh seal, as is stated.  Nero is not a player character, he's an NPC, and you're the crux of the story, not the NPCs.

The Charred Council, aside from promising loot in the form of 'reward' as is clearly stated, is working on the ideals and desires of the characters.  You'll notice, no doubt, that no 100% Heaven or 100% Hell characters are in the Core, nor even any standard Gilgamesh members.  If the characters want humanity and Earth to continue existing as they are, they'll fight for the Council because they provide the best and most unbiased platform to do so.  Are some of the characters unabashed materialists who flick a genocide switch if it meant a bag of coppers?  Maybe, and they'll be catered to, but the real catering is being done to the people who want humanity and Earth to remain intact.

For instance, Souta is going to agree because he likes humanity living, thank you very much, and he hasn't always agreed with Gilgamesh's ideas about accomplishing that.  Lily might sign on because her life would be boring without humans to mess with, Fenn might sign on for the chance for a battle of his lifetime by fighting against multiple factions at once and participating in the biggest fighters therein, and so forth.

Of course the Council would utter such a pronouncement, particularly the head specifically noted to have an accusatory and demanding personality.  A character who refuses the offer will not be killed on the spot, but instead whisked back to earth with a brand to remind them of their treason.  If the agents of the Council meet with that character again in the future, there might be a fight.
