Irving certainly noticed the barrier outside the door, but he didn't pay it any mind. In his view, since he had already come this far, there was no need to concern himself with anything else. He had to gather the information he sought from the archive.
He began searching through the first few rows of shelves in the archive, looking for potentially useful documents. Soon enough, he found a file detailing a series of murders that occurred during a full moon. The protagonist of the murders was, of course, a human with werewolf blood.
At first, Irving didn't think much of it. He merely regarded the file about the full moon murders as evidence of the blood moon's power existing in the real world. However, after carefully reviewing the details of the case, he felt that the situation was more complex than he initially thought.
