"Did I hear time travel?" came the voice of a snow-white pony, who was just about to enter the library when he overheard the conversation.
"Isn't that spell like, really hard to do? Ooh, if your having trouble I've probably got something that can help..." he mumbled, turning his head to look into his bag, his spiky blue and black hair hardly swaying at all. He eventually found something, levitating it out using his magic. It was an amulet which if you looked close enough, there were engravings of gears in it that seemed to move... The whole thing looked not unlike that of a closed fob watch. He grinned, looking at the two from behind his sunglasses.
"A fine timepiece, but I wouldn't recommend using it to keep time. I'll show you how it works..." he said, pressing a button and flipping it open. The inside certainly looked similar to a fob watch too, but it only had a single hand, which was connected to a green ring which was placed behind a modified watch face.
"As you can see, it certainly doesn't show hours or minutes. Rather, when you push this button in the middle here..." he indicated the centre of the clock face, where the small rod holding the hand in place was poking out slightly, "It will double your magic. However, to avoid the unfortunate side-effects of the enchantment I have placed on the main component of this wonderful invention, it will only do so for a minute, and will then require ten minutes in order to recharge. Still, I believe you may find it highly useful... But, like all things, it comes with a price. A mere fifty bits sounds like a small price to pay for time travel..." he said, closing the watch and pulling it away from them, signifying he could sell it elsewhere if required. Inside, however, he was desperately hoping they would buy it; he was quickly running out of funding for his inventions, and would soon have to simply stop on his current project if it ran out completely.
