Deathstroke may or may not cooperate with the government; I haven't decided yet. If he doesn't, he'll be escaping to the city proper. Anyone in need of survival training tips, he's your man.

Xigbar is likely going to collaborate with the government and enjoy watching everything go to hell. He might be nice, though, and help people out in the Darkness.

Aslan is going to be roaming around the forests for the most post. He will also be out protecting people at night once the Darkness comes so if you need a bit of help, he'll be there to offer it!
