[@Dead Cruiser]: I'm still a little groggy from waking up late, but something else that immediately stood out to me was the mention of killing people from the Burial Agency.

They'd absolutely respond to that in force if they had even the slightest idea what was occurring and they're not a group you want as your enemies.

Also, I should have mentioned this but I struggled to fit it into the OP and forgot, but artifacts actually have a specific name system. It consists of "Title: Name", giving us things like Killing Edge: Muramasa or First Light in the Sky: Superbia.
