Here is Srükárum, servant of Sárku and lord of the Legion of the Despairing Dead... for James Maliszewski's Tékumel zine, The Excellent Traveling Volume #11, which is due out very soon.
I am not an aficionado of Tékumel. I never even heard of it until around 2012 or so. But I do remember seeing ads and/or mentions of Empire of the Pedal Throne, probably in old issues of Dragon Magazine. Here I wanted to keep with the sort of bat creature theme from the Book of Ebon Bindings. The text describes horrible fumes and smells so you can see that coming out of the nostrils and the mouth of the prince himself. And yes those are sacrifices tied together in the summoning squares, per the explicit details of the ritual from the Book of Ebon Bindings. Now you can summon demons too!
