The scene is an unutterably black jailcell somewhere in The Void. Morgoth sits quietly on his cot, hanging his head in silence. A sound of jackbooted footsteps echos thru the Void as someone approaches his cell. The figure stops and looks in contempt at the mighty spirit chafing in his confinement. He clears his throat. Morgoth looks up.

"Oh," murmured Morgoth, "it's you, Mandos."

Mandos stared at Morgoth for a moment, then shook his head. "Mail call," he said, tossing an envelope on the floor of the cell before walking away again.

The vanquished Vala seized the envelope and tore it open with the eagerness of a starving man at a Vegas buffet.

Dear Morgoth,

Fear not. Even though your efforts to take over Arda were unsuccessful, you still may be of use to us, teaching our agents in the field your methods and procedures. We are concluding our preparations to squash Eru into an ectoplasmic grease spot on the floor of Valinor. Be patient, and we will have you released as soon as our operation is concluded.

Signed,
