It roared into my ears

A beast of ferocious might

It fails to stick to a set height

Its moldable form allows it flexibility 

Though with enough ridgedness to bring swift humility

Don't be alarmed by its mean description

It's a safe haven for many living in its jurisdiction

A master of change and an advocate for resistance 

Nothing stays the same under its persistence

Have you guessed its name? Its title? Its proclamation?

The ocean should never be mistaken!
