The Circle of Columns is a system agnostic introductory adventure set on Tékumel.
from the introduction
The adventure was originally a Kickstarter stretch goal, released before the publication of our Béthorm: Plane of Tékumel RPG. It is designed without specific game mechanics in mind. GMs may fill in whatever specifics are needed to run this adventure using their game system of choice. The creature descriptions include a ‘danger rating’ in ( ) after their name, indicating the number of beginning player-characters it should take to exactly match one of those creatures in combat. Those GMs who run this scenario using one of the available Tékumel gaming systems may of course use the appropriate creature stats.
The adventure is set in the northwestern frontier of the Empire of Tsolyánu, from M.A.R. Barker’s world of Tékumel.
The reason for the PCs coming to this place is also left open-ended. It is up to the GM to work out reasons and motivations to bring the PCs here.
