Baius
Father? Don't make me feel old. You're right; that feeling isn't normal, especially if I can't sense it at all. It has been, in this lifetime, at least, but it was much warmer in my memories.
The cathedral has been transformed from what I remember, and even as Gaius, I wasn't allowed to see most of it.
It shouldn't be in use. I've traveled through the underground roads many times before, but that building has been transformed into a stronghold, so even its underside is disconnected from the rest.
