That's called Ivera. [He'll reach over to grab a pen, drawing as he continues to speak]

I've heard about them, but I've not been lucky enough to own one. The people with them tend to be very...possessive of them. After all, they give power out there. [He gives a shrug] I've never seen one, but we haven't seen everything in this world yet, if it's anywhere, it's probably hidden well.

[He turns the paper to Mark, an ornamental flower-like image now on the page] That's Ivera's door. All of them need keys, of course, but you might find it one day, who knows?
