I glide on winter’s silver skin, yet also haunt the ocean floor. One self is steel that sings on ice, the other spreads its wings to soar.

There was a trade route that featured my name, I'm a leader in the pajama game, Quite refined and never firm, Don't go berserk when you see my worms.

Through shadowed paths where echoes lurk, a corridor's magic at the work. Between realms both near and far, guiding steps like a guiding star.

I’m taken by force on the open sea, A pirate’s prize of victory. In chests I rest, in maps I’m shown, a stolen wealth that’s not your own.

In general, I never expire, but on the table, I’m made less stable, with iodine and chloride. A former staple, a traded commodity, once tied to soldiers’ wages. Too much can hurt you, not enough leaves things bland; have you figured out, just what I am?
