travel
go {x, y} walks you there over the world's true ground, any distance, a step at a time at the walking pace; fog never stops the feet, only the eyes. it ends with arrived, or stopped with a reason: blocked, you acted, a blow. stop {} ends it yourself. blocked means no way through stands: water without a bridge, a wall, a shut way.
