cypher[]
The runes in the background are in fact English written using a cypher Here are this strip's sentences in order they appeared:
BURN THE WORLD
DESTROY ALL LIFE
HATRED IS LOVE
CODED MESSAGE
IT'S A SECRET
YOU HAVE TOO MUCH
TIME ON YOUR HANDS
THIS IS SMALL
WODBUBBLES BLAR
DARK BM IS MEAN
ALMOST DONE
GETTING OLD
JUST ONE MORE
AFTER THIS ONE
THANK GOD
IT'S OVER
This cypher has appeared in other strips too, like the one before this one, where it says BURN THE WORLD HATE IS LOVE all crissy-crossy, and here, where it says I AM THE MOST EVIL CHARACTER IN THIS COMIC I WILL DESTROY REALTIY, and somewhere else, I think, so it might be useful...
The cypher (not every letter is there though)
