Guardians of vessels, their mighty shield, Where waves crash and secrets are sealed. My first part a place where ships find berth, My second a divider, made of stone, brick, wood or earth.

In some hands a weapon, stronger than any blade A marvelous invention, one of the best ever made A variety of dreams can I create, And yet with different meaning I enclose with a gate. What am I?

I have a mouth but I don't eat. I have a bed but I don't sleep

Intelligent people have me A part of the learning curve But when you destroy me It sounds like you found me. Did you find out?

Born with a brother, yet alone I stand. Among all the earth, I prefer the land. I speak with tongues but make no sound, My skin is worn where paths are found. I leave my mark, then fade from view, Where I am, there you are too.
