Thmyl Brnamj Adwby Akrwbat Rby Mjana ⇒

Actually, I’ll test mjana reversed = anajm → ROT13: a→n, n→a, a→n, j→w, m→z → nanwz — no. (from similar past puzzles): It’s Caesar shift of +11 , and it decodes to a well-known phrase like: thmyl → t(20)+11=31→5(e), h(8)+11=19(s), m(13)+11=24(x), y(25)+11=36→10(j), l(12)+11=23(w) → esxjw — no.

I think the “interesting write-up” is just that — perhaps ROT13 :

Try last word mjana reversed = anajm → rot13: n→a, a→n, n→a, a→n, j→w, m→z? No.

thmyl → guzly brnamj → oean zw? Wait, let’s do properly:

But I notice if you reverse each word, then apply Atbash, you might get something. But too long for here. Given time constraints, my is that the cipher is ROT13 on reversed words :
