[ Zelda has considered asking the fairies for more information about how things work around here, but sometimes it seems like they're just as confused as the dreamwalkers. ]

I must admit that I have not investigated this happening very closely. So many things in this world seem to happen with no impetus whatsoever. The arrivals and departures of other dreamwalkers, for example, always seem to come as a surprise to the fae, as do dreamshifts. They appear to understand what is happening well enough, but I do not believe they control it.
