Mystical Unicorn Portrait

Did you see that? A shimmering, glimmering being at the edge of the wood? Quick! It’s already disappeared! The trees seem empty and dark, but you run through the branches, desperate to confirm the hopes you dare not put into words. Ah! A light bounces off the pond! Looking up, you see a majestic, glowing entity drinking from the crystal clear pool. A kaleidoscope for a mane, and a gleaming horn as reflective as the water below it. Do you dare approach such beauty?
