Thowra: Spirit of the Wind
Chapter 4: Signs Of A New Enemy
When the two arrived they saw black sand everywhere but the sand wasn't taking any teeth or fairies. "Something is off." North said as they observed the sand. "Maybe because they're not Father's sand." A voice sounded out, making them look for the person or animal.
"There!" Thowra said as he pointed to a spire. On it was a boy, around Jack's age, with black hair, grayish skin, and yellow eyes wearing a dark gray cloak, a pale gray shirt underneath, and very dark gray pants.
"Who are you?" Bunny demanded until a Nightmare appeared in front of him. "Down Fallen!" The boy ordered while gesturing at it. The Nightmare snorted and moved away from Bunny and to the boy.
While they were trying to figure out who the boy is, Thowra saw something move in a shadowed part and went to see it. The second he got near, it lunged at him. He flew out of the way and saw what he now never wanted to see corrupted.
It was Jack except the hair was dark gray, his skin was paler, and his eyes were a very dark blue while wearing a dark blue frosted black hoodie, and very dark brown trousers with gray string at the bottom.
"J-Jack?" He said and caught their attention. "What in Manny is going on here?!" North demanded until he got a good look at the boy who spoke first. "You look exactly like Thowra!" He shouted and made the others look at him then back at the dark Jack.
"I'm Fallen Thowra," The boy said as he flew next to the other Jack. "This is Shadow Jack." The boy looked at them and just laughed. His laugh was different from Jack's, while Jack's was light and fun-filled, this laugh was heavy and evil-filled.
Thowra immediately went to Jack's side and was frightened yet shocked. "Soon Father will rise again and this time no one will be able to stop him." FThowra said before he and SJack vanished in Nightmare sand.
After the two left they went into the sleigh and went back to the North Pole, unaware of a lone spirit watching them.
I had this in mind but it was Pitch and he revealed everyone's Nightmare counterpart, so I thought of having Thowra's counterpart do the introductions. If you guess who was watching them I can add you as a spirit or a person. You choose.
