I'm looking for a fic where the gang decides to take Dawn and hide. I think they may have gone to LA but I'm not sure. I know it's not much to work with but it's all I remember.

Could be Pylea or Bust by Maryperk

It's probably not it, only because the Key is not Dawn, however, they do take the Key and run to LA (hoping to hide) and then enlist Angel's help to fight Glory in Unexpected.
