While I've never really posted before, I've been lurking for awhile and have read that a lot of DMs like their own home-brewed worlds. And, in reading I've come up with a question (it hasn't happened in any of the games I run, but I suspect it might soon). If a DM creates a world and the players create PCs for adventures within it and then the campaign ends, if the DM wants to run another campaign in that world at a later time-period, can he/she decide what happens to the PCs? In other words, are the PCs the creation of the players and thus their personalities and decisions are under their control. Or, can the DM just "decide" that after the campaign ended that this PC becomes evil, this one dies, etc. What do you guys think?
