Say, over the 3 months, woulden't details of events like the Arete Coup and the Maru's victory have circualted? I know that the Maru has because of the Mata Nui News, but I'm not as sure about the Arete.
By now, the entire island would know of the Daedra's attempt to seize power, and would be on the lookout for any of its members. Were Ketan, Anthyn, Embok or Dico recognized in any Koro, they would immediately be arrested. As for Decaia, Ta, and Kynaera - it's up to the individual players. Those Toa chose to defect from the Daedra and defend Ga-Koro, so it's possible that they are in the clear. Depends on the Koro, though - if I were Hahli, I wouldn't let them come within twenty bio of the front gate, regardless of how "changed" they were.
