(I wanted to do this for a Role Play prompt but not everyone likes demon Stiles and I got carried away, So this is it. I don't think I'll carry on with it. Cause it was just suppose to be a prompt.)
Derek kneeled down to pick up the discarded book, surrounded by the already solidified bodies of the witches, standing up he examined it. Unrecognizable symbols decorated the black cover, a heavy rusty-green lock keeping the book safe from unauthorized access; it was used to bring out a certain demon tonight, the night of the full moon. Luckily, the pack had gotten the strange scent of moss and swamp water recently surrounding the town of Beacon Hills, signaling something strange was about to occur. They had quickly infiltrated the cavern just outside town, miles deep inside the forest. The battle between the magical creatures lasted for what seemed hours, before they finally had won.
"Deaton will know what to do with this." The older male informed, as he made his way towards the exit.
"I can take it!" The over enthusiastic teen piped in. "It's on my drive home."
Derek stopped glancing at the teen, deciding over that possibility.
"We already finished here, and we're all tired Stiles can take it Derek." Allison agreed, as she rubbed her sleeve against a sweat droplet forming at her temple.
Derek hated to admit that he was exhausted to the point his whole body hurt from the shocking blows of magic, stone, and summoned stoned creatures. He nodded handing the book reluctantly over at the teen.
"Get this to Deaton, don't open it." He said sternly, his eyes warning before letting the book go in the teen's hands.
"Got it, don't worry I'll do it and get home and finally get to have a normal teenage life without mythical creatures." He said waving his hand around. "A demon's the last thing I want to worry about." He assured.
When he arrived home, the first thing in his mind was "what exactly is in this book." Before trying everything to unhinge it, a broken crow bar later, he had the book flashing open. The moon still shining high above the sky activating it quickly as the ritual was about finished, all that was needed was a host. An evil crackle surrounded the black smoke that had risen before diving towards the only capsule available. Sending Stiles toppling over it seeped into his open mouth. The blackness tasted of pure coal and ash, gasping around the suffocating fog before being able to breathe.
"Human? How interesting." The dark voice marveled.
Now here he stood, clutching the same book, in front of hale home, the clasp handing idly as it swayed in the wind. He knew he shouldn't have done it, but like always he seemed to let his curiosity run the better of him. He could have gone to Deaton, could have went to Scott, maybe if Scott wasn't too busy with Allison. While Deaton seemed like a good choice, he was scared beyond belief that the only way to get this entity out of him was some weird chicken killing ritual. So, he came here, Derek had his family records to help him, maybe he could help him without the others finding out that he couldn't be trusted with a simple task. He clenched his fists; before he let his knuckles make contact with the newly refurbished Hale house door.
