I'm trying to plan where all the locales might be (I know they can be anywhere), had you thought that this might share commonalities with Hadim near the Rimrock or Yeru near...?
I was thinking if Hadim was rhymes with At-them instead of A-spleen, it was a potential philological pairing with Tereghat, or maybe it is At-them to the locals and A-spleen to the Kar'Eld citizens.
I love the steppe demon-lord lore if you cannot tell.
