Anthony's day at the menagerie had started to drag once the last customer had left. About two hours before the shop was set to close. The owner had left a few hours before, knowing Anthony had his own set of keys and could lock up if she didn't return before closing. It didn't take two hours to feed all the animals or give them all water, even without magic. And so, Anthony stood behind the counter, just waiting for the time to pass. One of the cats plopped itself on the counter to be pet and he happily obliged. That cat had the best rubdown of it's entire life. Double handed!
When it came time to leave, Anthony made sure all the necessary cages were shut and locked. He breathed a sigh of relief once he was outside of the shop, the lock clicked tight on the door.
And then the air turned frigid and it became hard to breath because of it. Everything just felt cold, down to his very core. Anthony turned to look and came immediately face to face with a Dementor. He barely had time to shout for help before the thing was touching him. It wasn't trying to kiss him, but the tug on his mind was unmistakable. Anthony froze. He had no magic to fight back and the Dementor had him trapped, stealing memories. Anthony tried to hold on, make it hard for the Dementor to take what he was trying to, but before he knew it, the memory was gone.
And the Dementor's hood was being lowered, showing off it's grotesque mouth. The pull he had felt on his mind had faded to the background as the Dementor pulled on his soul, tugging to break it free. Still, all Anthony could do was make choked sounds from the back of his throat as he fell to his knees, his voice frozen and unable to scream for help. He could hear screaming though, in his head. Sounds of battle, the school collapsing around him. No distinct voices though, everything was a blur and all mashed together. There was something missing from the memory or sound of the voices but he didn't know what.
His knees buckled under him, unwilling to hold up his weight any longer and Anthony tipped to the side, splaying out on the ground, unable to fight off the thing trying to steal everything that made him... him. That made him happy. It was just the sounds of screaming now, and his own whimpering.
