I gather terms and keep them in play. Without me, the order breaks the rules. On the field, I set who faces who, a quiet frame for every matchup. Numbers lean on me, teams trust me.

Knowledge I impart, Sometimes solely from the heart, Other times it's from the mind, I'm finished with the bind

I swallow explorers in twists of endless dread, Minotaurs lurk where walls whisper lies, One wrong path and bones join the forgotten, Yet solved I free the mind from its own prison.

Shell of stone with tongue of silk, I hide a secret none can milk. I open only when I choose, Guarding pearls the oceans bruise. Silent at the water’s rim Name what I am, tight-locked and slim.

I’m laid down but never sleep. I get walked on, yet I don’t complain. I soften steps and silence rooms. What am I?
