Patience and also... USE THIS TIME TO DO THINGS YOU NEED TO.
Become the lighthouse NOW so the abandoned world can find her shores.
This is the prep time before the final boss battle. Level up, gather ingredients, get the best armour (the full armour of god will do), build the strongest team and learn everything about your final boss. Games make for good analogies, huh?
"Perfectly healthy" people don't suddenly get sick and die.
They can be poisoned acutely, but chances are these people were very sick already and just never noticed. You'd be amazed at how much people don't notice about their own bodies.
Stop trying to wake people up. Wake yourself up first (nobody's there yet), and let people arrive at their moment by themselves. Or not.
