Hey,
Now for the record I actually am one of the players in this campaign and I joined the boards pretty much for the purpose of defending my Gm's statements and to clear up some confusion. Though for the record I was not involved with the SNAFU that Bibliophile20 outlined.
The main problem was that this was meant to be a simple event. PC's leave the library, see a strange janitor and leave the library with a sense of dread. Then we'd get back to the regular scene. Instead, our wizard, who is more of a power player than an RP'er got paranoid and the GM told him (through an awareness check) that the janitor was a zombie. He panicked, fried the zombie, the malevolent force turned on the rhythm and they fled. Once out of the building, still in a panic the wizard levitated them "out of harm" and onto the library. For the record, the wizard has something of a "Molly Carpenter syndrome" and thinks that magic can solve all problems (this was the second time in the scenario that he had tried to use levitate, the other had talked him down the first time).
So yeah, personally, I couldn't have come up with a better option in the situation. But yeah, the situation went off the rails and things got a little haywire. Just wanted to clear up any confusions and say that this guy does know what he's talking about.
