Ren had a rather pragmatic way of looking at Aterat and its people. He assumed many of them were brought here, just like they were, and that they just didn't remember. Some of them seemed to alien to one another, even the structures were as dissimilar as they were the same. It was hard not to think of this place as something akin to Mementos, which made even more send to the boy since he could summon his Persona here.

The teen spent the time Waver was away going over the notes again, sketching out a rough diagram of exactly how he wanted to lay out the field he was thinking of and around the building he was thinking of, leaving any distinguishing marks from his illustration.

Following Waver's return, he nodded as the professor directed him to recreate the effect with the supplies provided. After he had everything set up to the best of his understanding, he reached one hand up to touch his mask, the other he extended toward the miniature closed magical circuit. He didn't know if his magic would work this way, but the design he'd created itself gave him something to focus on, and in a way it was sort of like activating his third sight.

The circuit wavered before the energy he summoned flickered into place and he smirked.

"Nice."
