Sadly, my Tekumel gaming hit a speed bump when I discovered that 54mm "scale" does not necessarily mean 54 actual millimeters, and that "54mm scale" manufacturers are just as wildly variable as the rest of the industry. That effectively derailed my efforts mid-summer, and I have yet to get things moving again.
Instead, I re-focused on larger 60mm figures, in a non-Tekumel, Hyboria-campaign-inspired effort, which can be found over on my Lohwand blog. HERE.
I am considering 60mm Tekumel, but only in a vague sort of way...
