(Don't) Dance with Fey

Comes with a short horror story I wrote https://www.deviantart.com/nerva1/art/1192388768
Couldn't fit it here so the beginning below:
The cold hands of a wooden creature covered the eyes and ears of a young woman. Their long fingers had a tight and harmless hold over her face. Another arm gently pulled her shaking body closer to themselves, to the old hollow tree, further from the gruesome scene unfolding just three steps away.
It all started when the first son of a lord, the heir of the nearby lands, unexpectedly arrived to the village. With a smile on his face he invited the youth to his castle to participate in the incoming celebration of spring. Many cheerfully agreed and among them was her and her friends. He urged the excited crowd to take horses and carts and follow him. On the way to the castle he abruptly turned from the well-trodden path, instead he head to the forest that stretched on the left side of it. “The first ceremony will be held there. Stay close to me and don’t get lost”, - he said.
They went deeper and deeper, the forest got thicker and thicker, the carts could hardly go through. “We’re so close, just leave them. Follow me on foot if need be”, - he said again. And so they left the carts and kept up with the young noble as best as they could.
Eventually they arrived to a secluded grove within the forest, at the center of which stood a lonely withered tree. “Over there! Leave the horses and join me there!” - he joyfully proclaimed. Most folk hastily followed him, while others tended to their mounts tying them near a good bunch of grass. The young noble strode to the old tree. A few weathered stripes of fabric were wrapped around its branches, quivered with the wind. He stood and glanced at the people surrounding him then theatrically reached to the top of his doublet and pulled out a little wooden flute. Some quizzical looks laid eyes upon him. “My grandfather gave it to me...on his death bed. At first I thought what a pointless gift that was. But one day out of boredom I played it, a couple of notes. And afterwards… Well, you’ll see for yourself.” - he uttered. Dead silence settled over the grove for a moment as the young man readied to play. A long sound came from the flute, and then another, and another. Something trembled, crackled within the tree, as if it was awoken from a deep sleep. The bystanders gave a gasp of terrifying surprise. Suddenly a similar melody echoed from far around them. The young noble played a much more festal and cheerful tune that time. Like in response the mysterious instruments sounded right behind the crowd.
The magical fey creatures appeared all over the place, little fauns, nimble satyrs and beautiful nymphs, some were picking up the music with drums, blowing horns, the others wildly danced rejoicing every moment of it. The people’s bodies also unwillingly reacted to the rhythms of the enchanted tune, at first they simply tapped their feet, the sensation would spread to the legs and then the whole body started moving in accord. “Don’t be afraid and don’t resist. They are the utmost esteemed guests in our lands. Please dance! Dance with them!” - the young man loudly spoke.
Many invited charming nymphs, the more curious and brave fellows stepped in with the satyrs and fauns, a few kept it between themselves, the undecided one cuddled to the old tree, trying to restrain herself, worriedly glancing once in a while at her friends.
The festivity continued with great animation. A thin figure of a nymph approached the young noble. From the outside perspective, it seemed they recognized each other. The nymph offered her hand, and he warmly kissed it. She gently smiled. He tried to move away with her from the prying eyes, but she didn’t budge. Instead she wrapped her arms around his body, leaned into him and whispered: “You also accepted to dance”. For a moment he lost his facade, a perplexed and slightly worried look crossed his face. But a couple seconds later, he regained the outside confidence. He nodded his head, grabbed her by the waist, and together they started to waltz.
The strange scene was witnessed by the lonely young woman, even more she grew suspicious of the whole performance. She wanted to share her idea with the friends however while she had been preoccupied with the strange couple, they (the friends) dissipated somewhere amidst the raving party. Not long she was peering over the crowd looking for them – something approached her from behind. For a second she thought it was one of them. As she looked back and was about to say something in sigh of relief, three pairs of pale eyes stared at her blankly. She was startled by the wickedly shaped tall wooden creature. It seemed as if three human-like upper bodies made of bark, branches and wood were fused together. It had three long arms and two legs. Some leaves and flowers were decorating its otherwise terrifying look... (continued in https://www.deviantart.com/nerva1/art/1192388768)
