Warlocks loved Halloween, it gave them opportunities to try out more outlandish spells without making mundanes aware of their existence. Anything 'spell out of the ordinary' would be deemed as a trick or a treat depending what was conjured during the month of October. While deemed rude to use these spells on other unsuspecting Warlocks, the rest of the downworld, mundanes and Shadowhunters were fair game for hijinks and good source of fun.
Warlock Kris Pulfur recognized the tall raven haired Shadowhunter immediately, he didn't care that the Nephilim was a Lightwood and that he held some important post in the Shadow World. Shadowhunters were fun to mess with in general. The bonus with this Shadowhunter was he's the lover of the High Warlock of Brooklyn, Magnus Bane.
Kris chuckled to himself, this would be the best prank and Bane wouldn't know who had gotten one over on him. He had to be careful with his magic so that he would not be detected. He knew which spell to use, he had several powders with him to help with his prank. A Warlock who loved doing pranks for Halloween was always prepared. The best part of his spell was once the Shadowhunter was within Bane's magic, it would activate thus making Magnus think he had turned his lover into a cat. It would take the High Warlock some time to figure it out and Kris loved the idea. He was going to do a dance later on at the Hunter's Moon and wait for the gossip about what happened to the High Warlock's Shadowhunter.
Kris made himself look busy, as if he lost something and was searching his pockets and waited for the Nephilim to walk by, then blew some magical dust toward the Shadowhunter and whispered his spell. He waited to make sure both landed on the Lightwood male, then walked in the opposite direction.
Alec Lightwood was walking home, it felt good calling Magnus' loft home. He could have asked his boyfriend to portal him home but after the day he had, he wanted to walk off the tension and stress of running the New York Institute. He had glamored himself; while he was invisible to mundane eyes, the glamor didn't work with downworlders but he seldom ran into any that he was aware of while heading home.
Alec noticed a guy who appeared to be searching for something but didn't give him anymore than a glance as he made his way down the street to the loft. After walking past, he felt a tingling sensation down his body, it felt like magic but when he stopped and looked around he didn't notice anything out of the ordinary. It wasn't the same feeling as Magnus' magic but he still knew when magic was around him. While keeping a mental note of the oddity, he shrugged off the feeling and continued to the loft.
Alec entered the loft, hung up his jacket, stored his weapons and called out to Magnus. He felt the magic that was part of Magnus surrounding him, gentle in an embrace which made him smile before retreating back to its master. He wasn't in the room more than 30 seconds when his perspective changed; all of the sudden he was closer to the floor and everything looked bigger. In fact, he could smell all sorts of things he had never scented before, he shook his head to clear his mind, then padded further into the room and was surprised to see how big the couch and tables were and he suddenly had an urge to scratch the couch.
Alec's feline instincts took over and he sat down on the floor in confusion. He looked down at his paws, paws? He has paws, black fur and a tail! He immediately got up and followed his tail around in circles trying to get a better look at it and he wanted to catch it too. He stopped when he got dizzy. He tried to clear his head and think, what had happened? He didn't know what was wrong but something wasn't right. He shouted Magnus but unfortunately that came out as a really loud howling meow. He did it again and again until Magnus was in front of him. He looked up at the giant sized Magnus Bane with pleading eyes to help him.
Magnus was shocked, there was a cat in front of him mewling out as if the animal wanted to talk to him. The cat was gorgeous with the most amazing hazel eyes he had ever seen. It was the eyes that made him suspicious. They were too close to Alexander's eye color.
Magnus looked down at a beautiful black cat, he wasn't sure if he had ever seen that eye color on a cat. The cat was lithe but had some muscular build and he could tell by the face the cat was male. He had never seen this cat before and the fact it was in his loft and not on the balcony was odd. He fed the strays on the balcony, he never let them in the loft, he had too many things they could get into or worse they could get hurt by knocking over potions or other things cats shouldn't be near. He was reminded of when the red haired cat was in his loft and ensorcelled guests with their fears at Max's rune party, Iris Rouse had invaded his home to steal his spell book and call in her blood oath with Clary Fray. It was possible to shape shift into a cat, though he never found a reason to do so.
"Hello there," Magnus cooed at the cat, "what are you doing in here?" Magnus looked at the cat to see what it would do, he was certain it was a warlock wanting to talk to him. There was no other explanation for the cat to be in his loft. The cat just stared at him expectantly, a silent plea in the eyes to recognize him, to help him in some way. The cat mewled and moved slightly toward Magnus and sat back down in expectation, a gesture to encourage him to do something.
Magnus reached out to the cat to see if the animal would come to him, he held out his hand so that the cat could scent him and while he wasn't surprised the cat immediately took to him, the friendliness of the cats movements toward Magnus made him wonder. The cat closed its eyes and rubbed earnestly at the Warlock, clearly feeling comfortable with him. The black cat then circled Magnus and finally wrapped himself around Magnus' arm and curled his tail in feline ownership. The cat looked back up at Magnus with love in its eyes and with the long blink of his eyes stating 'I love you' by the feline; Magnus froze. It couldn't be and if it was, how? How could his Alexander be a cat?
Magnus picked up the black cat and held him to his chest, the cat purred and leaned into the Warlock. This was what Magnus wanted, the cat wouldn't know he was checking his body for magic or any other indication that this cat was in fact Alexander Lightwood. It would be easier if the cat could talk to him. This idea made Magnus smile, he might not be able to give the cat a voice but he could link them telepathically so that he could understand the cat better and if it was his Alexander, find out how to fix the problem.
Alec loved the way Magnus was holding him, the petting, the rubbing of his fur and being so close to his boyfriend. Magnus always smelled good but with his cat like senses he was discovering more things about his lover in general. Being with Magnus meant his current cat condition would be resolved. As much as he loved this type of attention, he would rather be in his own body and receiving this type of attention. He was purring and that was a funny feeling in his throat, he had never purred before and it was a soothing sensation. He noticed his lover checking him over in general for injuries or something but he didn't care, he was being held and it was wonderful.
Magnus did notice a faint trace of magic on the cat, and noticed some dust on him as well. At first he thought maybe the cat had rolled in the dirt outside but dismissed the thought. This dust had magical properties. It was time to find out if this beautiful dark beauty was his, "Alexander?" The cat looked up at Magnus. While cats could answer to certain sounds, Magnus was certain that this cat knew and responded because he was his Shadowhunter.
"Oh darling, what happened?" Magnus couldn't believe it, the cat's hazel eyes just blinked at him. "It's alright, I'll fix this and then we're talking about a protection spell for you." While Magnus was scolding him a tiny bit, he worried about his lover far more than was comfortable for him. The cat shook his head in agreement. Pleased with the one sided conversation, Magnus took his Alexander to the study so that he could start searching for the right spell to turn the cat back to his Nephilim lover.
