Without more clues, I can’t decode it fully, but the cipher looks like a or a polyalphabetic cipher with a short key like “solid” or “paper”.
“tn yw yp na tyal ab knyl myqtsm” – no English. danlwd nt wy py an layt ba lynk mstqym
danlwd → dwlnad nt → tn wy → yw py → yp an → na layt → tyal ba → ab lynk → knyl mstqym → myqtsm Without more clues, I can’t decode it fully,
Given that “solid paper” is the title, maybe the ciphertext decodes to something like: or similar. Without more clues
But “dan lwd” might be a name? Doesn’t fit.
