"Is it you, Rose? You may come in." Arriving at the guild master's door, he looked a little dismayed. I can imagine how he's feeling right now, losing so many powerful and promising adventurers.
Wait, we haven't confirmed their deaths yet. Don't think of something like that, that's a lack of respect.
"So how's it going?" As soon as I walked in, I asked directly how your little investigation. He had already gathered some information from the adventurers who had visited the dungeon, but it still wasn't enough.
"I've spoken with five guild masters that I have contact with, and none of them have ever heard of a dungeon that disappears like this. Even more, dungeons that swallow adventurers and disappear."
"I see, there's no record anywhere about a dungeon-like this?"
"No, in any document or book I've looked at, something like this has never been cited, it's something completely new."
