By have a massive dimension-spanning epic adventure to save the multiverse, culminating with superheroes, fantasy adventurers, and spacefarers battling a tarrasque, a lich, and a demigod on the rolling surface of a Federation starship orbiting Sigil, the City of Doors and center of everything.
After starting off fairly typically in our 5E campaign, things went suddenly, terribly awry as the world was shattered and PC's were scattered throughout the multiverse. At this point I handed each of them a PC from some time in their gaming past, worked out using Marvel Heroic Roleplaying rules (which is a great system for doing something like this. Since this was a plenary session for the gaming group, there were no less than 11 players present, with PC's or NPC's from every game campaign I have run since I arrived in this state. In the gaming group itself we had
From the 4E D&D Campaign
- Aukan, the Goliath Warden
- Grendel, the Minotaur Barbarian
- Skyhawk, the Pixie Rogue
From the Marvel Heroic Campaign
- Abrasax the Guardian Gargoyle
- Bubblegum, former teen hero
- Union Galactic, cyborg cowboy
- Positive Crisis (who showed up later to be played by Union Galactic's player)
From the Mass Effect Campaign (run by John)
- Xavier, the human infiltrator
From the Firefly Campaign
- Thyme, former Companion
From the 5E D&D Campaign
- Roghanj, the Dragonborn Sorcerer
- Calidis, the Elven Druid
- Robin, the Genasi Fighter
The main villain was Positive Crisis' evil brother, Negative Crisis, who had contacted a plan to lure the Star Eater from my Star Trek one-shot to destroy Sigil and use the TARDIS (from the League of Extraordinary Dudes one-shot) to recreate a universe completely under his control. He was assisted by a group of villains from the various fantasy and superhero campaigns, along with lots of minions. It was an over-the-top rollicking time, a real change from the "kobolds and copper pieces" that are the staple of Dungeons & Dragons. Frankly it had been a long time since I had put this much work into a single adventure, and it really showed.
Anyways, it was Ben's last night, so we had one more group photo before he heads off into his next adventure. Juggling 11 players might be at ton of work, but it is all worth it.
