The forest

(Rough draft, needs refinement.)
 
One day Iraeon and Aeren are skipping school, Iraeons idea, he'd do it often. He wasn't enamored by the idea of learning, he just wanted to have fun. Aeren was top of every class, there was nothing she couldn't do, but her brother had worn her down and she went along with it, she's ahead on every subject, what harm can taking one day do?
 
A few hours later, the twins are enjoying the fresh air and some sun, when they hear a sudden screech a little ways away. They both had a deep love for birds, and recognised the sound as an owl in distress, and headed towards it. They came across a group of 5 poachers hunting in the woods, and an owl on the ground, hooting softly and covered in blood.
 
Aeren was livid, she flew into the angriest rage Iraeon had ever seen her get, she had a temper, she'd alway had a deep fire in her, but this was something Iraeon had never seen. She points at one of the men and he instantly lights on fire, the crackling sound and smell of burning flesh radiates the air, and she turns her gaze to the second, he goes up in flame too, she turns her gaze to the other 3, each in turn and one by one each alight. She collapses on the ground as Iraeon rushes over to the owl, seeing if he could do anything, but it was too late.
 
As Iraeon picks the owl up and pulls it into it's final embrace, he looks over to Aeren who's shuddering on the ground. She looks up at Iraeon and says "I'm so cold brother." Then Iraeon watches in horror as she alights in flame, her scream piercing his heart. Iraeon, paralyzed by fear, watches, unable to act, as his sister turns to ash. He lets out an equally piercing scream, and his hands alight in blue flame and incinerates the owl he'd been caring for. Iraeon collapses, and the last thing he sees before the darkness takes him is blue flame where his sisters body had been moments before.
