The elf thought for a moment, then said "If there's a way to save Santa, then we should do it."
"Then I'll wish that the Darklyte should be destroyed," Jon said. "Unless, of course, you think I should wish that the invasion never happened ..."
"No. There's no telling how that might change history. It might make things worse. But destroying the Darklyte here and now can only be a good thing."
"Okay," Jon said, nodding. "Then I wish that the Darklyte was dead and that Santa had his own pure soul back."
The stone glowed, granting his wish.
