Through which all the shit 'everybody' ever lost fell into. Billions of skate keys report cards homework wallets house keys illegal drugs car keys pens glasses priceless paintings treasure maps lucky pennies monkey's paws....you get the idea.
All that crap including stuff from all the other species of the multiverse went flying through them starry images above.
I'm tell'n ya you can't make shit like this up!
...eh, try not to fall in.
