Minecraft idea of madness

My brother came up with an idea for a use for my ridiculous Minecraft world.  I'm honestly not sure if its brilliant, insane, pure genius, or just plain madness.  He and his friends are starting up a Dungeons and Dragons game. His idea was to use my Minecraft World as the setting for a campaign!  Apparently in the new edition (I've never really played), you need visuals or maps or something.  Sounds like a neat idea to me.  AND it gives a purpose to my madness!!!  (insert maniacal laughter here)
