Mnemonic

Your leg leaves muddy footprints on the floor of a religion's ancient temple. The monks try to mop them up, but the trace of your steps remains — a perfect trail leading right to the sacred altar you weren't supposed to find.
Additional thoughts
Picture your bare leg stepping through a candlelit temple, each footprint impossible to erase. The religion's monks are horrified because your trail exposes the secret path to their holiest room. Trace = leg tracks through a holy place.
Quick recall
A leg stamps footprints through a religion's temple — an undeniable trace of your path.
