With the combined help of Chihiro and Damiel, it won't be a difficult task to get nearby and narrow down the location to a few possible places. The difficulty will be in getting inside, as the center is below ground and there's three buildings (more or less) that could possibly contain the underground center and only one, a small doctor's clinic, is remotely open to anyone.<br/><br/>The less inviting of the other two is a Guildhouse used for... well, it doesn't say for what, just that it's owned by the Guild. The doors are barred, and the whole place is made to look unattractive to anyone that would like to snoop inside, lacking any kind of windows or other apertures into the place. There's not even a hatted opening to let smoke out, so the place looks about as uninhabitable as possbile.<br/><br/>The more inviting one is some kind of private meetinghouse. It has a pair of bouncers, a small crowd going in, and a sign that helpfully names the building as the home of the Iron Circle of Thaumaturges. Most of the decorations on the sides seem legitimate, but it would be hard to tell at such a distance. Especially because they could hide more work inside what appears to be a 'mistake' at this distance.
