DewPour's Message

DewPour must deliver a message to all four clans FireClan,PollenClan,GlacierClan and MistClan, the young tom worries too much he becomes selfless and self centred, what's the message "Before there is peace, cats will crumble storms will come, rivers running with blood..." what could it possibly mean?! You can trust no one, not your own kin...
