I've been playing in one of Kat's campaigns for 10 sessions now. I can't recall when I've had so much fun playing D&D. Like me, she is a "Lore Nerd" and we have collaborated from character creation until present providing each other with tidbits we've discovered over the years playing in the Forgotten Realms. Kat weaves such an intriguing tale and portrays NPCs with so much detail that you feel you know them and want to be their friend. And she will match the effort you put in and up the ante. If you come to their table with an elaborate backstory, you will see elements cropping up here and there in the overall story. This makes all the effort you put into defining your character so much more rewarding. The more you put in the more you will get out. I've played TTFRPs since 1978. I've been in hundreds of campaigns with dozens of DMs. I'd put Kat in the top three without hesitation. I can't recommend her highly enough. The level of immersion is unsurpassed. I find myself looking forward to every session and dreading each one's end.
