I'm pretty sure this isn't what Renee was asking for, but it is what I came up with anyway.

You started with a spark. Small, smoldering, but you are not the type to stay unnoticed for long. You slithered up siding and coiled around drapes, feeding your hunger until your power was unstoppable. We quailed before you, ran from your rage and stood in awe of your terrible beauty. You laughed at those who tried to quench you, stood tall and furious in your rapture, a halo of light and heat. You danced in your shades of red, yellow, orange and gold, but kept the blue heart of yourself secret from our astonished eyes. You rolled, undulated and leapt before our dazzled faces. Graceful and languid, you broke apart and came back together, a seamless merge of heat that baked my face and brought moisture to my eyes. You arched into the dark sky, gathering oxygen to fuel your ravenous unending hunger. As your unstoppable appetite consumed, you belched dark oily smoke into the air. It drifted poison fingers too close to my lungs and I coughed, my body struggling to send the toxicity back into the air, the sky, where it rose up to hide the stars. Your dangerous dance usually enchanted, but that night it left me in tears. You are not containable, you are untouchable, and I cannot trap you in a bottle or box to bring to show and tell. But you are wonderful, you are terrible and I will survive you.
