Thmyl Brnamj Sewergems M Alkrak -

brnamj → jambrn → “jamb” + rn? sewergems → gems + sewer → “gems sewer” — “gems” reversed is “smeg” — “smeg” is slang, “sewer” reversed is “rewes” not word.

Maybe it’s a simple letter shift: Try ROT13: thmyl brnamj sewergems m alkrak

But “sewergems” reversed = “smeg rewes” → sounds like “smeg” and “rewes” maybe "smeg" (from Red Dwarf) and "rewes" → "sewer" backwards. brnamj → jambrn → “jamb” + rn

“alkrak” reversed “karkla” → maybe “karkla” = “karkla” nothing. thmyl brnamj sewergems m alkrak

So final:

t→g, h→u, m→z, y→l, l→y → guzly — not clear. Could it be is in “thmyl” scrambled? Rearranging letters: thmyl → myth + l → “myth l”?
