Tabletop role-playing on an exotic alien world of high science-fantasy!
from 'What is Béthorm?'
Béthorm is a science-fantasy tabletop role-playing game set in Professor M.A.R. Barker’s World of Tékumel...
“Béthorm” is also the Tsolyáni word for a pocket dimension. Tékumel’s solar system exists in just such a pocket dimension, and this game was designed using the Pocket Universe role-playing system.
