Dude. Total faux pas.Princes of the Apocalypse (DM): I've also attempted this one twice. The first time was running it piecemeal and skipping around with my college gaming buddies when we got together a few times a year. They focused on one elemental prince and did a dungeon related to that prince each time we'd get together over a period of a couple years. Ultimately there was an epic showdown with Imix - and it was amazing. The other time I tried to run this I was running it with my girlfriend and her family, including her dad who had gotten her into the hobby when she was younger. He hadn't played D&D in probably 15 years, and it was awesome. Then I killed her family with a random encounter with gnolls. And we broke up soon afterwards - so that game ended.
I like to think the breakup was unrelated to the TPK. Everything worked out in the end ultimately. We patched up and stayed friends. Even ended up DMing her in my Tomb of Annihilation campaign, and my wife and I attended her wedding last October. I had a cigar and bourbon with her new husband and her dad - whose character had died in that gnoll encounter.Dude. Total faux pas.
