The land of Fungham is known for its mushrooming business and peaceful countryside — and lately for several things that have no obvious explanation. A child has gone missing. A demonic witch has taken up residence in the woods. Gnomes are stealing socks with apparent intent. There is also a pig king, the specifics of which are best left for later. None of these things were here before. Something brought them. The ancient gate in the mountains nearby may be the common thread connecting all of it.
