Notes from the Thursday Night Group was originally a booklet printed in limited copies and sold at the U-Con gaming convention a decade ago. The booklet is written as a series of vignettes that offer a rare glimpse into both the everyday events and the secret rituals that are intrinsic to the vast and richly detailed world of Professor M.A.R. Barker’s Tékumel. These stories were taken from games played by the Thursday Night Group in Professor Baker’s home. Rather than entire game sessions, these are highlights taken from gaming sessions that include a day at the Hirilákte arena, witnessing a midnight ritual of the mysterious Pé Chói, notes on the hideous hybrid people of the Nyaggá, and a detailed account of a ritual of revivification and an after-death experience in the Isles of Teretané.
