Bound in Flamekeep, Bel Shalor is the most infamous overlord in Khorvaire, largely due to his well-documented devastation of Thrane and subsequent defeat at the hands of Tira Miron. Bel Shalor embodies our fear of one another and the capacity for even the most virtuous person to do evil. He thrives on paranoia and smiles when a good person harms an innocent or ignores their conscience.
Bel Shalor’s speaker is the ak’chazar rakshasa
Durastoran the Wyrmbreaker, and his minions are a
powerful force within the Lords of Dust. Though his
influence was originally tied to Thrane, the conditions
of his binding now allow him to influence anyone who
draws on the power of the Silver Flame; it’s entirely
possible he wanted to be bound and always planned to
become the Shadow in the Flame.

Most of the overlords of the Age of Demons are truly bound, unable to affect the world in any meaningful way. A few have frayed their bonds, however, and have found ways to influence Eberron even while bound. In the modern age, Tiamat is stirring in the Pit of Five Sorrows, rousing dark emotions in the hearts of dragonkind. More important for Khorvaire, another overlord schemes. Seven centuries ago, he nearly escaped from his bonds. The paladin Tira Miron defeated him by becoming a vessel for the Silver Flame, but the overlord never truly returned to his slumber. For centuries he has lingered in the heart of the Silver Flame, whispering to the weak-willed and manipulating the path of the Prophecy to bring about an age of darkness. He draws strength from every feud and every act of betrayal, and the discord of the Last War increased his might significantly. If he breaks free, chaos and despair will surely follow. He is Bel Shalor, the Shadow in the Flame. Some scholars claim that he is one and the same as the deity known as the Shadow, and that he taught the dragon Ouralonastrix the arts of magic at the dawn of time.
While he is bound, Bel Shalor has little ability to directly influence the world. His power is one of insidious inspiration, of whispers in the dark. He has turned his prison against his captors, reaching through the bars of the Silver Flame to touch the minds of the faithful. Some followers of the Flame have been corrupted to actively worship Bel Shalor. His strength is his ability to trick good people into performing evil deeds, something he has accomplished all too often over the millennia.
These statistics reflect Bel Shalor’s physical power if he is released. These combat abilities are just a fraction of his power, however. If the Shadow in the Flame is freed, his influence will begin to extend out over the land around him, first covering a few miles, and ultimately spreading out across an entire nation. People who fall under his sway become selfish and cruel, turning on one another instead of standing against him. PCs are immune to this passive effect, but it might affect their ability to find allies. Within this sphere of influence, people grow pale and their shadows become clearer and more vivid even in poor lighting, often seeming to move of their own accord. It is said that the shadows conspire against their owners, telling Bel Shalor of their secret plans; you must decide if this claim is true.

The brightest soul casts the longest shadow. You can’t escape the evil within you. It’s always one step behind, waiting for you to miss a step. Even if you keep your footing, do you truly believe that those around you are as strong as you? Are they so virtuous? Or have they already let the darkness in?
The overlords embody mortal fears, and Bel Shalor embodies our fear of other mortals—the eternal suspicion that a stranger means us harm, that even our friends can’t be trusted. Bel Shalor thrives on paranoia and feasts when fear drives good people to do terrible things. Wars feed Rak Tulkhesh, but an inquisition that torments countless innocents delights Bel Shalor—especially when carried out by virtuous people. In the third century YK, Bel Shalor nearly escaped his bonds before being bound once more by the sacrifice of Tira Miron, but some sages wonder if Bel Shalor didn’t in fact allow himself to be defeated. Now he is forever tied to Tira, and anyone who can hear the Voice of the Silver Flame can also hear the tempting whispers of the Shadow in the Flame.
Bel Shalor doesn’t encourage savage violence. Instead, he amplifies fears and suspicions while fanning the fires of greed and self-interest. He convinces us that the people around us are cruel and petty; the only way to survive is to strike first, to take what we need regardless of the cost to others.
Corrupted cults can appear anywhere; Bel Shalor seizes on a suspicion and amplifies it. The Whispering Flame is a transactional cult hidden within the Church of the Silver Flame—a secret order of priests and templars who do Bel Shalor’s bidding in exchange for power and influence. The greatest agents of the Whispering Flame rarely perform obvious acts of corruption themselves; instead, they subtly encourage others to compromise their principles or succumb to their fears.
Forces. Bel Shalor’s chief agents are rakshasa, and his prakhutu (“speaker”) on the Council of Ashtakala is known as the Wyrmbreaker. His minions specialize in stealth and deception, not brute force. Bel Shalor also controls shadows, and it’s said he can grant malevolent life to anyone’s shadow, causing it to spy on the person who casts it or even to kill them.
Gifts. Magic items associated with Bel Shalor typically are used to manipulate others, conceal thoughts, or control shadows. Important members of the Whispering Flame often receive a ring of mind shielding, and may use eyes of charming to influence others. Such items are typically made by the Lords of Dust, though they can be ancient relics or items infused with the power of the Shadow in the Flame.
Character Ideas. Bel Shalor thrives on manipulating thoughts and emotions. A bard of the College of Whispers could attribute their gifts and magical talents—the ability to harness fears and even steal another’s shadow—to a bond to Bel Shalor. For a warlock, either the Archfey or the Great Old One could represent the Shadow in the Flame. Members of the Whispering Flame sometimes begin as paladins or clerics devoted to the Silver Flame. Even once serving Bel Shalor, they are able to retain a connection to the Flame and keep their class abilities; however, they typically shift to the Trickery domain or the Oathbreaker oath.
Story Ideas. Any fear could be amplified by Bel Shalor and form the basis of a cult. A group of people in a small town might become convinced that there’s a doppelganger or a wererat hidden in the community that has to be rooted out at any cost. Or perhaps it’s a fear of foreign spies. Or warforged made to replace humans . . . can you prove that you’re not a warforged imposter? Frequently such cults truly believe that they’re protecting the innocent from a serious threat, and don’t realize that they are the ones serving a dark power.
Similar stories can be associated with the Whispering Flame. Cultists work to trick truly virtuous members of the church, convincing good templars to persecute innocent people in pursuit of imaginary threats. This situation—good people harming good people—delights Bel Shalor. Can adventurers expose the true agents of evil without killing innocents themselves?
