Ghuleh and Jigolo Har Megiddo are both the names of Ghost songs and the Death Priest is dressed like Papa Emeritus... so it's fairly obvious that this is all just one big Ghost reference. One of the previous chapters was titled "If You Have Ghosts", which is a Rory Erikson song that Ghost did a cover of.
The author is obviously a rock/metal nerd, since there are chapters named after Iron Maiden songs, and characters like Ky, whose full name is Kyuss A. Sevenfold. The shopkeeper is named Riff, which is a reference to guitars, one of the boys from the village of Brethren is named Slash, like the guitarist from Guns and Roses. And those are just the most obvious references.
