They are talking about a Black Swan event. Diana Larkin's latest video talks about giants in the sea who will bring fire to the land, and that we should pray that their "firing mechanisms" will be deactivated.

She mentions that there are 5 giants and that our urgent prayers will stop their fire throwing activities, and that we have a commission from the Lord to command angels not only to protect us but to command them to deliver us from all manner of evil. This means these black bombers lurking in the depths as well as exposing the swampies on land. God has given us the power to do this, to command angels.
