Cave Rubble Tee

Cave Rubble
 
Long ago...
 Late at night...
 Under the warm glow of my desk lamp...
 
 I scratched this symbol of unknown origin into my notebook with
a Sakura Marker. I do not know what it means, and I do not not intend 
to ever understand, nor could I if I wished. All I know is that when it
spoke to me, it said its name was......   CAVE RUBBLE.
