Sebastian couldn't tell how much time had passed or how many times he'd rewound the clock.
Each rewind felt like an eternity, a blur of moments dissolving into an indistinguishable haze that left his mind feeling frayed and his soul yearning for a solid foothold in the shifting sands of time.

The knowledge of the ballistas had become so ingrained in his mind that he could now assemble and disassemble them with the effortless precision of a master craftsman, even in the darkest depths of night or in the throes of a fever dream.
However, keeping memory of this was going to be a problem, hence why he wanted to learn Miles' spell.
