Here we stand in Death's Chamber, waiting for the final blow to fall.
Young and old, throughout the fold, the gas strikes down all.

Majdanek Gas Chamber. From this hole, canisters containing Zyclon B, the material that released cyanide gas, were dropped into the over-crouded room of Gypses, Jews, Poles, Russians, Armenians, Jehova's Witnesses, political enemies of the Nazis, asocials, homosexuals....

Pretty much anyone who was "you're not with us, so you must be against us!"

NEW INFO: Those blue stains on the plaster? Those are from Zyklon B itself!
