The mentions of the second goo attack have me thinking: what connections, if any, could be drawn between Lord Tedd and the current Voltaire-Pandora plotline? Dan DID say that the clog stuff was pulling on more plot threads than we realized, and my first thought after reading that was LT. Perhaps—and this is total speculation—Voltaire wants to stop Pandora because a magic system change would render this universe more susceptible to conquering. Of course, this doesn't explain why he wants to kill Elliot, unless Elliot or Magus has some as-yet unknown role in Pandora's plots (though that role would be irrelevant now, seeing as Pandora just did a 180).
