n→o (+1) a→r (+17? no) So not a simple Caesar.
Instead, try → orange: o (15) → n (14) is -1 r (18) → a (1)?? No, that doesn’t work. danlwd mstqym fyltr shkn khrgwsh narnjy Free
That looks plausible, as it matches a known cipher (likely a simple substitution or Atbash variant). n→o (+1) a→r (+17
Could be (A↔Z, B↔Y): n (14) → m (13) a (1) → z (26) r (18) → i (9) n (14) → m (13) j (10) → q (17) y (25) → b (2) → mz imqb — no. that doesn’t work. That looks plausible
