Devils, Demons, and The Bloodiest War


The next release from Wizards of the Coast is rapidly approaching. Mordenkainen’s Tome of Foes, a book all about the various, long-standing conflicts of the Dungeons and Dragons multiverse, looks to be a fantastic addition to fifth edition and it’s arriving on May 18, 2018, in game stores. Over the last few months, we’ve had spouts of information come out about the book, including the names of the six chapters within.

Leading up to the book’s release, I’ll be going over the six chapters, discussing the history behind each of them, and speculating about what new tales could be within!

This week, I’m looking at the Blood War.

Since the inception of the multiverse, law has fought against chaos. This battle has taken many forms, but none are as brutal and longstanding as the conflict between devils and demons. Known by all as the Blood War, this awesome piece of the D&D multiverse has an extended history, a ton of possible uses, and will be the expanded upon in the first chapter of Mordenkainen’s Tome of Foes!

A Summarization

The Blood War is a conflict as old as time itself, spawned from the utter vitriol and hatred between devils and demons, fiends of diametrically opposed alignments. Though the war is retold in many different ways throughout many different worlds, the story generally goes like this:

The first battles between law and chaos are remembered by few, but all understand that the Blood War stemmed from these initial wars. The war pits the inhabitants of Hell against the denizens of the Abyss. The former are devils, masters of law, manipulation, and might, while the latter are demons, creatures of chaos, madness, and inccessance. Both factions are fiends and inherently evil entities.

Unfortunately for the fiends involved, neither side has been able to vanquish the other, resulting in a stalemate. Fortunately for the rest of the multiverse, there is still no end in sight, for if the devils were to win, everything would be enveloped in orderly evil, and if the demons were to be victorious, all order would vanish and only madness and evil would remain.

This ‘endless’ war isn’t just arbitrarily without end for the sake of everlasting conflict and plot hooks. Instead, it’s a stalemate for a few, excellent reasons. 

First, the two sides counter each other far too well. The devils have fewer combatants but are more organized, proficient in combat, and understanding of war in general. Yet, there are so many demons that they devils are unable to wipe them out. As one demon dies, two more take its place, forevermore. Second, the demons of the Abyss are constantly fighting with each other. While archdevils plot in secret, waiting for the perfect opportunity to strike with minimal risk and backlash, demon princes attack their enemies without hesitation and care. Most of the time, it seems demons care more about gaining more territory in the infinite Abyss than slaying their mortal enemies. Last, some profit from the Blood War, such as a few archdevils in Hell and the yugoloths. They look to gain far more if the war were to continue indefinitely than if it ended swiftly with one side winning, and their actions or lack thereof proves this.

To summarize: The Blood War is an ancient conflict between demons and devils without an end in sight.

That’s cool and all, but how can we use the Blood War in our D&D games?

Using the Blood War as a Player

In most worlds, conflicts from other planes of existence spill onto the Prime Material Plane. The Blood War is no exception. If what you’ve read today sounded compelling, and you’d like to incorporate this bloody battle into your character in some way, you’re in luck!
  • A tiefling deserter of the Blood War, you’ve managed to escape to the Prime Material Plane with your life intact. However, your soul is still bound to your devil overlord, and she’s never let a deserter go unpunished.
  • Centuries ago, your ancestors made a pact with an ice devil to serve in the Blood War for tremendous power. You are the first of your line in three-hundred years to be free of this burden, but your family’s history has been shaped by it.
  • You discovered a relic of the Blood War a few years ago. While you know its origins, you’re sure its meaningless and forgotten...until demons begin to assault your dreams.

Using the Blood War as a Dungeon Master

Without the Blood War, there are still a plethora of ways to use demons and devils. However, with it, your fiends can have a deep history, a current and interesting situation, and a reason to seek the aid of adventurers. Looking for some plot hooks involving the Blood War? Look no further!
  • A pit fiend gifts an adventuring group an explosive weapon of immense power, on the condition that they infiltrate Demogorgon’s lair and use the weapon to cause the lair’s collapse. Will the party carry out the bargain, or betray the devil?
  • Demon cultists believe the key to winning the Blood War is hidden within the blood of the monarch’s youngest child. Are they right?
  • The god of justice decides the time has come for the Blood War to end and sends his angelic legions into the fiendish realms. Will he succeed? At what cost?

What’s Upcoming?

So, I’ve discussed the Blood War’s current history, and various uses for it as a player or a dungeon master, but what might we see in Mordenkainen’s Tome of Foes about this extraplanar melee? 

I hope to see a plethora of the combatants in the Blood War, from archdevils to demon princes (both of which are confirmed), as well as new demons, devils, and yugoloths. In addition, I hope they ‘update’ the Blood War’s status, meaning, I hope they throw a wrench into the mix. Perhaps Lolth has found a way to end the war or infiltrate Hell, or Asmodeus is prepared to assault the Abyss with all his strength. Finally, I’m really wishing that they’ll include various tables of plot hooks, villains, and character traits involving the Blood War. The tables they’ve included in their recent books are fantastic and ooze inspiration, and I’m really hoping for more in this book.

Next week, we’ll be talking about ELVES.

I’ll see you all then!

D&D Players and DMs, Be Thankful

It’s Wednesday night. The party are faced with a decision: continue toward the lair of one of their vile foes through cramped kobold tunnels, try to enter through a broken lightning rail, or turn back and face the enemies behind them. If they choose correctly, they’ll reach their destination before the mysterious Vaxilidan can complete the domination of those they hold dear. If they choose incorrectly, their loved ones will become horrific husks twisted by aberrant minds and incurable darkness. Of course, they choose the quickest and safest path: through the kobold tunnels! In single file, they crawl and slip their way down the wet passages until they arrive at a hole that leads into an ancient and flooded crypt. Dragon murals line the walls, kobold packs float in the murky water, and the cracks in the ground remind the party of a defeated foe. Their path forward muddied, they decide to delve into the crypt and a wild night of roleplaying and mad speculation ensues: kobold sarcasm and

How to Begin a D&D Campaign

The world is created, the characters are made, and the starting location is set, but how do you begin a Dungeons & Dragons campaign? There are many lines to check off on your list. Is the starting point created? Are all the session zeros finished? Is the initial plot formulated? Is the opening scene ready to go? As I prepare for the start of my next D&D campaign, Caught in Galen, I’m going to help you or anyone else out there itching to begin a campaign correctly complete their pre-campaign checklist. The D&D Campaign’s Starting Point Where will the campaign begin? This is a key question you should know before your players begin to make their characters that I dedicated an entire article to awhile back. Will the party explore the titanic ruins of a dragon empire on a jungle continent? Will they delve into the depths of the Subterrane in chase of a rogue celestial? Will they begin caught in a giant city of an inherently magical population? Know this before anything e

How to Play an Archfey in D&D

Archfey are part of the god-like trio: archfiends, archfey, and great old ones. Each member of this class is unique, from Mephistopheles the Lord of No Mercy and Orcus the Prince of Undeath, to Hyrsam the Prince of Fools to Dendar the Night Serpent. Distinct from even these unique examples, archfey live on the Plane of Faerie, or the Feywild, where they play court and war amongst each other in a land of impossible flora and fauna. Most of the time, they won’t appear directly in your campaign. They’ll be faraway actors, pulling the strings in the background as your party traverses the world. However, what if you would like an archfey or three to become major players? What if you’d like to use Oberon the Green Lord as a villain? Maybe Titania the Summer Queen as an ally? How about your warlock forms a pact with Hyrsam the Prince of Fools? Well, you’ll need to know how to play one. Outlined below are how I see archfey in my world, Eldar. They might be different in your setting

My Take on Matthew Colville’s 5E Action Oriented Monsters

Soaring into a manifest zone on their airship, the Misty Tide, the party erupts into a pocket of the Elemental Plane of Fire high above a sea of bubbling lava. Surrounding them are hissing fire newts mounted upon burning birds, prepared to hijack the airship and release the fire elementals powering it. The airship’s captain screams, “Hold out! We’ll escape ‘ere in a minute, I’ll get us through!” In response, the fiery raiders attack, lead by a striking fire newt warlock. The combat begins, and she thrusts her molten scimitar into the broiling air. The blade soars between each party member, scorching them with ease before reforming in her hands. Later in the combat, she deftly descends atop her burning bird below the airship, narrowly avoiding a blast of eldritch energy. In the struggle’s final moments, she dismounts from her tiny phoenix in a whirl, leaping thirty feet to gouge one of the party members with her scimitar and deal tremendous damage. Ultimately, she fails; the rest of
