Belphegor - A demon of Sloth and Greed
Buzurivambavas is Bastard Demonspeak, and comes from the true Demonspeak bzhuu’vhambv’s, which means “carrying and crawling one”, or “one that carries and crawls”. They are a subtle kind of demon, and do not exhibit the terrible rage and bloodthirst of some other demons.
The court wizards of Angolterre have been working for several generations to protect the dynasty. They see to it that the new monarch's names acronymically refer to a rune of protection. Once completed, the rune will make the dynasty almost invulnerable in battle, wise in counsel, etc. Unfortunately the next name, the only one that starts with the right letter, happens to have belonged to the worst monarch in living memory. Not much chance of getting the current ruler to name his child that, or for the people to put up with it if he did! What's a court wizard to do? The magic requires that the plot be kept secret of course...
