Prospero (Uninvited Guest)

Prospero was a particularly callous and evil Eternal. For fun, he and others of his race descended upon an uncivilized world and bestowed the inhabitants with technology far in advance of anything they could comprehend, then retreated to the higher dimensions to watch the ensuing carnage as the primitives horrifically misused the technology and killed their world.

He arranged for a grand ball in the ruins of the wasteland for several Eternals to gather and amuse themselves by observing the few relics he had saved from the doomed world. In a separate table, a lonely Time Lord sat, quietly indicating he had brought a gift, but harshly condemning Prospero and the other Eternals for so cruelly destroying an entire civilization for nothing more than amusement. Prospero was less than thrilled to have his actions censured thus, and he and the other Eternals raised to pounce upon the Time Lord and feast on him.

That moment, the Time Lord revealed his gift - a crystallized fragment of the Time Vortex.

Dropping the crystal on the floor, a time storm swept away the Eternals, destroying the ballroom. When everybody managed to wake up, they realized the Time Lord had destroyed their Eternal essence, sweeping them into the fold of Time, giving them a single, mortal life. Now they could learn the value of that which they destroyed with such contempt. Prospero and the other new Ephemerals were left speechless and stunned as the Time Lord left, their new bodies struggling to comprehend what had happened. (DWM: Uninvited Guest)
