Chasm of the forgotten

What do you do to fix worldwide problems? Well, you send someone down a magical chasm of course! Nobody has ever returned from the journey and the only indication that it was successful, is that the problems magically disappeared. For the past 200 years, no one has been able to complete the journey. But now, with the population on the cusp of violence and the leaders distrusting each other. It's time to send someone down again as a last ditch effort.
