Possible Rebman game for next year's ACUS!
A group of the Aoife enter the Afanc Glass to question Alyse, find the resting place of Lir's bones, desecrated by the Chaosi several centuries past and steal back the Vorpal Blade from a cunning guisel.
Once in the Labyrinth, the Aoife find the Cheshire Puss in the midst of exploring R'lyeh to wake the Great Ones to destroy the Fomoire, but this act may undo a balance 1600 years old.
Will the foundations of Rebma be saved?
...very much not a Cthulhu (ka thool hoo) adventure. "In his house at R'lyeh dead Cthulhu waits dreaming."
