Oh, not in cruelty, not in wrath

The Reaper came that day;
An angel visited this damned sat,
  And took the parapen away.

Replaces parapen with sleepypen that contains 30u of sleeptoxin and 30u of a new mutetoxin that makes you unable to speak.

Mutetoxin can be made with 2 parts uranium + 1 part water + 1 part carbon.
