I have a security job, but I do not have a break. I am often seen in farming fields.

I ruled the land, the sky, and water, My history was a glorious chapter, My reign was long, a world of terror, now remains kins with feathers.

My first three watch closely, never blind. My next three keep sharp judgement in mind. My last dwells in water, a cryptid out of sight. Together, I testify and make the truth come to light.

I'm a process that's vital, in plants I'm key, Converting sunlight to energy. Water and carbon dioxide, I take in with glee, Producing glucose for me and oxygen, for all to breathe.

In the night sky, a cluster bright, sisters sparkling in celestial light. Born of myth and ancient lore, a stellar gathering to adore. What am I, among the stars, guiding sailors from afar?
