On a personal note, a huge thank you to Greg Tito, Bart Carroll, and the rest of the Wizards of the Coast team for making this idea become a reality. They believe in their product, the message of togetherness that TTRPGs represent, and took this beardy little DM's idea for a fun cross-podcast event and turned it into a reality. So, again, I say thank you. Sincerely.
