"I can see how that would destroy any romantic notion about titans." Regulus turned toward Levi. "We have giants and half-giants. They normally don't deal with people. In fact, because of Muggle- non magical folks expansion and wizarding rules, they have been pushed into a small corner of our world. There they have ended up killing each other."
He frowned, trying to calculate the numbers in feet. "Our are about twenty five feet tall, so that's about... seven and half meters, I think. We can kill them with magic. We can do lots of things with magic."
He nodded. "No, I get it. It's why the magical ministries of our world make a point to protect those without magic by pushing them out of populated areas. They live in isolated regions." He shrugged. "We don't have those either. They tend to stop working around magic. It's why I rarely use mine. If I start doing lots of magic around electric stuff... well it breaks. Maybe not here, because this hotel seems to have its own magic."
