The world is indeed full of peril.

Three Rings for the Elven-kings under the sky,
Seven for the Dwarf-lords in their halls of stone,
Nine for Mortal Men doomed to die,
One for the Dark Lord on his dark throne
In the Land of Mordor where the Shadows lie.
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
In the Land of Mordor where the Shadows lie.
He paused, and then said in a deep voice,
"This is the Master-Ring, the One Ring to rule them all.
This is the One Ring lost many years ago,
to the great weakening of its maker's power.
Now, he greatly desires to have it again,
- but he must NOT get it"
