Yeah, we had a near-TPK with our group recently. The rogue picked a lock and opened a door, which triggered a comical amount of explosives. We dealt with the consequences, but it was frustrating because it just kind of came out of nowhere. It didn't seem to be that kind of campaign, y'know? Nothing remotely like it happened in months of play up to that point.

...so I was kind of reading my own experiences into this. :P
