The place where Mister Roy resided was right in the middle of nowhere, quite literally, he stayed in a small underground area while building something on top of the said underground structure. The building had a unique form and strange design, one that Reyn couldn't understand.
Weren't all houses built with four walls? Why did Mister's house have more than four, then? Also, isn't a house supposed to have a ceiling? Plus, what is the strange platform in the middle of the house? Maybe it wasn't a house at all? If not a house, then what was it?
Reyn couldn't understand it and had no way to know. Actually, he could ask Mister Roy, but he was scared that questioning him too much would piss him off, and thus he'd get mad at Reyn or try to throw him away again, so Reyn kept all his questions to himself.
