624) [Did to players last night] At the end of the night, after an evil villain (in my case, a goblin monk) is descibed as having sold his soul to gain a way to truly destroy the PCs, have the players be unable to discover exactly what happened, where he is now, or what's going on.
Then begin asking for Will saves and rolling dice. Ignore the first few -- no response, no matter what happens.
Finally, at the end of the night, make one more round, note anyone who beats, say, 20, and then wait for a good opportunity to take control of the PCs to say the following:
Player1 (made save): Hey, everyone alright?
Player2 (made save): Yeah, I'm okay, but what happened to Player4?
Player3 (failed save): Player4? What are you talking about? That guy died in our very first adventure all those years ago when that goblin monk came in out of nowhere and killed him.
Tell Player4 that due to a slight alteration in the time stream, he will now be playing a dwarven wizard, and not a human sorcerer, since his human sorcerer died at second level several years ago.
Then thank them for a great session, pack up your books, and leave.
625) [which, frankly, the players just did to themselves] Let them figure all this out about a half-hour after they just killed the Succubus who sent the goblin monk back in time, and who is the only creature that had the power to send the PCs back in time after their enemy as well.
