+For years, your bones have lain in disarray, scattered about the mausoleum where you were interred.
+Some foolish mortal wandered in to your burial chamber and put you back together.
+Now, you can wonder around spreading chaos and destruction where ever you go.
+First, however, you have to make it past the dead so you can plague the living.
+You will nead some kind of weapon to make it through.
+You spot a grave digger's shovel and quickly grab it even though it's covered in rust.
+You give an evil grin, oh wait, your a skeleton, your skull is always doing that.
+
