You seem to like the whole Altar of Roots bit. Why not keep it simple and do
THE ALTAR OF ROOTS as the name? If that's a main part of the game anyways. That way you don't add anything new really for people to remember, you just cull the part that people get confused by.
Or flip it, and do THE ALTAR OF ROOTS: Bevontule ? Then you get a simple pronouncable name that people can tell their friends, while keeping everything you wanted? Plus, a freaking root altar grabbed my attention. Sounds awesome.
