Demons of The Lesser Key of Solomon

Dungeons and Dragons v 3.5 also have some juicy Ars Goetia.

Here is an image of Vepar, as interpreted by theDURRRRIAN  

Not the most "faithful" interpretation of Vepar, as the artist acknowledges, considering the crazy descriptions of some of these Dukes of Hell.  Not quite like the giant sea-monster you were expecting from the Bloodstained E3 Demo, eh?

^Human spine for a whip, you say?

A human's spine would be a perfect crafting ingredient for the Vajra lightning-sword of Indra!

To avoid being totally off-topic, here's an image of Barbatos (the 8th Duke of Hell who likes to appear as a "bearded old philosopher")

Source (This image oddly reminds me of "Guard Daos", the final boss of Lufia & the Fortress of Doom for the SNES)

Risada Holy crap... Orias is one bizarre fellow, even for a Lesser Key demon duke.

Here's one artwork that I've found.

Murmur (Shin Megami Tensei series)


Murmur is a Great Duke of Hell, and commands 30 legions of demons. He teaches Philosophy, and can command the souls of the dead to appear before his conjurer to answer every desired question.  Murmur once went by the name "Matthias" (perhaps the developers of Bloodstained could take some creative liberty with this detail?).



Murmur is usually depicted as a soldier riding a vulture or griffin (or even a hippogryph), and wearing a crown.

I've found out that "Murmur" in Latin means "noise, whisper, or the sound of a trumpet".


Hey!  If Murmur's an enemy, perhaps the sound of trumpets playing could "announce" his arrival to fight Miriam.

According to TinEye, the site ww38.devilsfoe.com/ is the oldest one having this image, so even if its forbidden link there, it could be the source.

Ooh, holy necro of a great thread! How I missed posting here.
