Doom To Those Who Read This Message.

caverns carved into the rock,
terrible champions of the land,
are summoned to protect,
great treasures and secrets.

evil secrets cannot be kept,
eyes see and lips speak,
enter here and never return again.

and the gatekeeper now appears,
ready to receive admission.
a shadows gem, the black cloud of darkness and doubt,
or the precious metal bar,
worn, stolen, forged, and fought over.

these will suffice enough,
and the master will be pleased enough,
to arrange your meeting with fate.
