Indigo just nodded when his questions were answered. This spell was only for inanimate objects, not living things like people. Though there were other spells for that. That made a lot of sense, and Indigo wasn't surprised at all. Now he was a bit curious about what the spell would be that could be used on people like Indigo's questions had been about. Maybe he could ask later, or try to find something about it in the library. For now, though, he neatly wrote out a few more notes as Professor Darlington spoke.

He found it very interesting that the incantation had to be modified depending on the object. It was even more interesting that the modification depended on what the original form was, not necessarily on what it was now. That meant that you first had to know what the original form of something was before you could turn it back. Like glass. Indigo gathered from context clues that the original form of glass was sand, and now that he saw it he did remember hearing something like that before but he didn't think he would have been able to remember that on his own. So he never would have been able to do the reversion spell on something that was glass without first looking it up. He just thought that was interesting.

Why did they have to stand? Indigo was perfectly capable of practicing the spell while sitting at his desk. But he reluctantly got to his feet. Which one did he want to practice on first? His eyes landed on the bread roll first so he decided to go with that one. Why not? He repeated the incantation under his breath a few times. Prima Forma Siligo. "Prima Forma Siligo." As he said the incantation he made a counterclockwise circle in the air, ending with a point to the roll. And suddenly it was no longer a roll. It was... wheat? It didn't look quite right, but it was wheat-adjacent. Hey, it wasn't bread any longer.
