This is a new topic for one-parters. Given the nature of the group, I don’t expect it to get used very often, but here’s one, from the Chaosium “We Are All Us” free adventures commemorating the death of Greg Stafford:
Session 1 - Call of Cthulhu: The Lightless Beacon: And not, as some of us might have hoped, Spring Break on Booty Island.
Session 2: Mythic D6 - Bastion: Guest GM Jerry D. Grayson takes the Wharties through a nice straightforward job, buying the thing and bring it back. How hard can it be?
Session 3: Definitely Wizards: We are taking the final wizardry exam! Only one little problem…
Session 4: Overdue: Library assistants go to collect an overdue book. How hard can it be?
