Turn Hostile npc back to friendly

Does anyone know if there is any way to make hostile NPC friendly again, after accidentally attacking them?
It looks like i accidentally hit one of the mages in Neera's camp with a spell or something that made the whole camp turn hostil. Sadly i have overwritten any previous saves before finding this out.

I know you can charm them to talk to them, however it's a bit hard to charm the whole camp, especially since Neera can't hold that many charm spells in her memorization slots.

I'm hoping there's a Global or something that could be edited? or perhaps a console command that makes them friendly? Sadly Ctrl+q only makes them friendly while in the party, once they leave they are hostile again.
