Hall of Infinite Doors

This door seems a lot more normal than most of the other doors you've passed by so far. A little dusty and cracked up, but it looks safe enough.

Someone was obviously too lazy to bother making a sign for the door as the word 'Undertaker' has been carved into the wood.

The door handle looks disgusting. It's rusted over and has broken cobwebs draped around it. So, do you open the door?
