Abandon hope all ye who enter...

The words on a piece of wood on the ground next to a cave... probably left over from a sign that stood or hung nearby.  As you try to look into the cave you can't help but feel that you are being watched.  Beady eyes peering from undisclosed locations.  Not sure of your safety and security you step back and that's when you notice the carving that had blended into the rock formation until now.

The letters are haunting etched into the rock above the cave. They appear to be inset with  some sort of dye or rust.. wait... a chill runs down your spine as you realize the letters above the cave are engraved and inset with blood.  Abandon all hope indeed, for this is the home of the "Legion of Doom"
