A Kingdom of Death and Despair

Once upon a time, there was a half-witch of three
who walked on the land where creatures roamed free.

Once upon a time, there was a prince of one
who danced with the waves under the sun.

Once upon a time, there was a prince of two
who hid amongst the shadows where fear only grew

But when time became impatient, a prophecy was conceived of twins born of darkness
who would live their lives aggrieved
but coupled with their misery was the answer all sought
but the question remained, which one would be left to rot?
