In the quaint village of Elderswood, nestled between rolling hills and whispering trees, there was an ancient library. The library's charm lay in its collection of forgotten tomes, which were filled with cryptic words and embellished illustrations. One rainy afternoon, young Clara stumbled upon a particularly worn book entitled The Secrets of the Enchanted Grove. As she flipped through the pages, she discovered a passage that spoke of a mystical creature known as the Wisp. The text described the Wisp as ethereal and elusive, appearing only at dusk and capable of transforming its form. Clara's heart raced with excitement as she read on, but she was puzzled by a particular phrase: 'The Wisp danced through the woods, a luminescent figure, darting among shadows like a flickering candle.'

While Clara envisioned the Wisp's shimmer, she wondered about the word 'luminescent'. In the context of its use, what does 'luminescent' most likely mean?
