Happy New Year!
Right after the new year, I started "The Siege of Castle Rend" by James Haeck, from MCDM's Strongholds & Followers. Served as DM for three friends and my brother. We had a fantastic time and everyone developed an instant crush on Pinna the hedge mage. Great art in the book and I really like the adventure.
Right before the New Year, I served as DM for 5 characters at level 17. Very different game. They sat down at a negotation table with the archdevil Zariel, a solar, and an empyrean. Then the superpowerful Elder Brain at the center of the rogue planet (which is actually a feeding ground for an illithid colony under the surface) attacked everyone. The party survived and now they're a few hundred feet from the outermost edge of my multiverse.
