I am the guide that shapes the game, Dictating how it's played, setting the frame. In structure and order, I firmly reside, Guiding the players, keeping them tied.

Some find me confining, a burden to bear, But without me, chaos would fill the air. I bring clarity, fairness, and control, Ensuring competitions run as a whole.

Within my grasp, boundaries are set, For every participant, a fair etiquette. Observe and abide by my guiding light, And the competition will be just and right.

What am I, you may ask with a frown? A word of power, I am known as "______".

What am I?
