>TAKE BEAM
The doorway suddenly closes as heavy, immovable stones crush in from both sides.
You slowly and painfully suffocate in the Annex, cursing the gods for ever
revealing this horrible place to you. You wish you had told Craige about this
place -- that way, it could have been he instead of you.
**** You have died ****
But you can do this instead:
>PUT BEAM ON SLAB
Done.
>FIND BEAM
It's on the slab.
So now the beam is on the slab instead. Taking it from the slab still kills you, though.
